I have a V-8 Chevy and want to wire in a 6AL box that I have. I have already attached the connector to the MSD red wire, as shown. Since I will be using my Pertronix Ignitor as a trigger, which is wired just like factory points, I will not need to use this harness. The first step is to clip off the eyelets of the two wires that will be soldered together. These are very handy if you think that your plug wires will come into contact at any point with your headers. What should I open it up to. Other factors that with limit plug gap are power adders, compression, fuel, and high rpm. It was a 6al box with a pro-billet dist. Spark Plug Wires. Programmable 6AL-2 Ignition Control. I use plug wire boot protectors, as you can see here, as the clearances are rather tight in this application. I have already clipped the green wire and the black wire is shown here. It is best to route this harness away from the two coil wires and any spark plug wires. I found 2 issues that might be causing a no spark condition from the MSD ignition. Solid core wires will not suppress the higher spark output generated by the CDI. If you have any doubts about wiring an MSD 6AL into your system, you can simply download a PDF of the complete installation instructions, which includes simple wiring diagrams for all the most common systems, including points and/or Pertronix Ignitors. I will now be able to get the maximum voltage to the coil without removing the dash and coil feed wire.A third benefit, of course, is performance. In a nut shell, we were not getting spark out of the MSD box at cranking RPM. As long as Ol’ Paint remains Ol’ Paint, I will not be so fussy. Fortunately, the 6AL box comes with rubber mounts that actually hold the box about ½ inch off of the mounting surface, so irregularities in the mounting surface can be easily overcome. After drilling all four holes, loosely mount the 4 rubber grommets to the mounting location. As you can see by this photo of my mounting location, the sheet metal is a little less than perfect, due to a movable Ol’ Paint coming into contact with an immovable fixed object, courtesy of the previous owner. If you are concerned about the box being perfectly level, measure twice before you drill. Also found a partially burned wire from the ignition to the alternator.

I would run @ 0.045"-0.050". The larger the spark kernel the better, but when you start running more and more compression it is harder for the electricity to jump the gap, so you have to give up a large spark for reliability of the plug firing every time. After you have placed the shrink tubing over the fresh connection, light a match or disposable lighter under the shrink tubing. Punch holes in the paper after you have marked all 4 with a pen or pencil, and then scribe the mounting location on your car. I've got 2 x MSD 6AL + 2 x MSD (high vibration) Blaster II coils (fired by a Supertec twin-plug distributor) fitted to my 2.5 litre twin-plug engine. Now the distributor is connected, it’s time to hook up the coil. PN 6530. The MSD’s 8.5mm spark plug terminals feature “Dual Crimp” terminals. Set the cable aside so that it is out of the way. The mill features a Coast High Performance Stroker Kit, increasing the stroke from the factory 3.50 inches to 3.85 inches, utilizing Probe forged 302 pistons, and stock 351 rods and rod bolts. I noticed immediately that the car was much more willing to idle on cold start-up. What does every one think about this. I see there is an adapter plug (MSD PN 8869) for it, but was wondering if thats all you would need to get it to work. As you can see, the mounting location is not entirely flat. The Pertronix coil internally has 1.5 ohms resistance, which is required for certain systems. Before the MSD install, I had to feather the throttle a bit for a few minutes to get the car to the point where I could put it in gear and go. Note: Do not use digital or dial-back timing lights. A good quality, helically wound wire and proper routing are required to get the best performance from your ignition, such as the MSD Heli-Core or 8.5mm Super Conductor Wire. Since the panel that I am mounting the MSD box to will be replaced when Ol’ Paint becomes “New Paint”, I am not too fussy with perfection in the mounting. While the Pertronix system was adequate, the MSD-6AL box has some features that work really well for this application. A good quality, helically wound wire and proper routing are required to get the best performance from your ignition, such as the MSD Heli-Core or 8.5mm Super Conductor Wire. You can get these in large assortment kits inexpensively and they are always handy to have around for projects like this one, aftermarket gauges, and car stereos. he said "no, i thought it was to much so i gapped them at .045", so i … Before twisting the two wires together, be sure not to forget to slide a piece of shrink tubing over one of the wires. With the new coil in place, attach the orange wire to the positive terminal of the coil, and the clack wire to the negative terminal. This will be a good starting point, and I can experiment with different gaps later. I will get some decorative wire wrap to clean up the look in the coil area as time allows. I make the majority of my direct wiring connections this way, especially connections that I don’t anticipate disconnecting any time in the near future. At 14:1 you'll typically see the racing plugs gapped at around .028 -.32. Be sure your wires are properly spaced and routed correctly to avoid cross fire. This is what a freshly soldered connection looks like. Shown here is a two into one connector provided in the install kit. The line of MSD Blaster Coils, PN 8202, PN 8207 and PN 8222, are great for street and mild racing. This handy connector will allow me to easily connect the two factory wires to the one red MSD wire. My gap is at .035 right now. Not only will these wires make my engine bay look a lot nicer, they will prevent crossfire, provide a nice hot spark, and provide good radio static suppression. Make sure the terminals are fully covered, so that a live wire can’t come into contact with ground, shorting your components. Shrink tubing works much better than electrical tape, and is less likely to be adversely effected by harsh, under hood conditions. I will use the same method as I did when soldering the tach wire. I set my plug gap to .045, which is slightly conservative for a 10.5:1 compression engine. I bought the MSD 6AL box today - because I wanted a rev limiter - for my stock ZZ It that an IN- the-cap coil has ie small and yes the "extra" plug wire sucks!!!. The next step for me, and this is optional, of course, is to re-gap the spark plugs to a wider gap setting, to take full advantage of all that extra spark. I will get to those ugly plug wires in a minute. This is a simple one wire to one wire connection. Needless to say, the new module has all the advantages of an MSD ignition coupled with the size and look of a stock ignition module.

Gently tighten the nuts in place on the coil. The 6AL box has a rev limiter that has a small module that can be inserted to tailor the engine cut-off to your particular engine’s needs. People are often very surprised that you can still use a points style system with an MSD CD box. Also, I used to have a slight surge while cruising at freeway speeds when lifting off the throttle, or on very light acceleration, which I could live with, but it was annoying. Solid core wires cannot be used due to their inability to … With a hotter spark you can generally incraese your plug gap. Holley And MSD Created A Plug-And-Play Ignition For Sniper Users By Randy Bolig October 06, 2018 If you’ve been following along with the modifications to my daily-driver C10 pickup truck, you surely know that the install of a Holley Sniper EFI delivered a real improvement in drivability and fuel mileage. 1) TCW Wire Core is the ultimate solid core race ignition wire when RFI suppression is not a concern and when used with magnetos and point style ignition systems; 2) Spiral Wound Core (350 ohms per foot) when RFI Suppression is required for today’s complex multiple spark discharge ignition systems. This will aid in more complete combustion, and will help take full advantage of all the benefits that the 6AL provides. Nobody wants extra holes in their firewall. I haven’t put the car on a dyno yet, but seat-of-the-pants feel indicates that I have gained some horsepower. Now to the plug wire replacement, and to re-gap the plugs to the recommendations provided in the MSD directions. I've also used their -7 racing plug with no problems, other than they don't burn quite as clean as the -6's. This was an area that I thought needed help.Ford protects their stock coils from overheating by providing a resistor wire to the coil, reducing voltage in the run position from 12v battery voltage to about 8-9 volts. We still need to connect the heavy gauge red and black wires from the MSD box to the battery before we can proceed any further. That means to remove the resistor wire and replace it with a standard wire, you need to completely remove the dash. Buy them ahead of time so you don’t have to run to the store during your install.

Another method to scribe the 4 holes that will need to be drilled can be to make a paper template with the box on your workbench, as shown here. The MSD 6AL-2 Ignition can be used with most stock coils and aftermarket coils designed to replace the stock coils. The rubber grommets do a great job of making mounting location irregularities irrelevant, and they also help in air circulation around the box, helping to keep the box cool. Recently installed in the engine bay is a major update to the factory 351 Windsor two-barrel engine. Spark plug wire comparison between Accel wires, MSD wires, Magnecor wires, Mopar wires, and Granatelli wires. Note: Solid core spark plug wires cannot be used with an MSD Ignition Control. I called MSD today and they told me not to run the iridium plugs because they will get too hot. Please right click on the image and save the pic. MSDI GNI TI ON. The connections I made from the MSD box direct to the battery were also made the same way, as I had to add length to the wires to get them to reach. The orange and black wires from the second mini-harness from the MSD box are the wires that you will be connecting to the coil. Since high voltages no longer travel across the points, a CD box actually greatly increases the life of the points. And here is the completed look. Some tachometers need an adaptor to work properly with the box, and there is a handy Tachometer Compatibility List in the instructions that come with the box. For connections that are frequently undone and reconnected, quick connector or spade terminal connection will probably work a little better. MSD 6AL - large red wire to battery positive large black wire ... black wire to coil negative. 3. The box can be mounted anywhere, although a more remote location such is in the interior of the car will require you to splice and solder more wire into the harness provided, a fairly easy task. By checking the resistance of each wire you will determine two things: That there is continuity (not open) and if there is too much resistance in the wire. Spark plug wires are very important to the operation of your ignition system. Checked the resistance of the coil, checked out OK. After I got my CD box, and started the install, I decided to also order the MSD Blaster coil, which is a better fit for this system, and a nice new set of MSD pre-fit plug wires, which will perform well and look a lot better than with the old wires currently in place.On with the install! In fact, each foot of finished wire … Rather than leave bare metal exposed to the elements, I splashed a quick squirt of engine bay paint to protect the sheet metal from rusting when it gets wet. In fact when I first started running MSD ignitions. This particular engine should never go past 6500 rpm, and I prefer a 6000 rpm cut-off for added insurance.Another bonus is that the MSD box connects directly to your battery as well as your coil wire, and the voltage to the coil comes directly from the box, so the weak 8-9 volt factory coil voltage is no longer a concern. Spark plug wires can’t add horsepower (despite what some may claim), but they can adversely affect your vehicle’s performance. The Soft Touch produces a load-free rev limit that I am also going to switch over to the MSD Blaster coil, as it is better suited to the MSD system. We're frequently asked, whats the difference between all the wires that are available for my car ? The multiple sparks that occur with this box under 3000 rpm should greatly help start-up and low rpm drivability. Made both fixes, still no spark. The top slot is the tach output terminal, for those running a tachometer, and the Magnetic Pickup Connector harness at the bottom is for those running an MSD distributor or crank trigger, factory or aftermarket magnetic pickups. SPARK PLUGS AND WIRES Spark plug wires are very important to the operation of your ignition system. Since the factory wires originally connected to the coil, they had eyelets on them. Here I have crimped two spade terminals that I had in stock from a simple terminal set from the home improvement store. The plug gap is a little small for that mild of a motor. While the Coast Stroker kit is nice and affordable, one area where it under whelms is the stock rods and rod bolts. Note: Solid Core spark plug wires cannot be used with an MSD Ignition.. The first feature that is really attractive is an adjustable rev limiter. MSD IGNITION • www.msdignition.com • (915) 857-5200 • FAX (915) 857-3344. It would be a good idea to download the PDF ahead of time so that you can order any necessary adaptors at the same time that you order the box. And here are the wires connected directly to the battery. -The Heavy Black wire of the MSD must be grounded to the battery negative terminal, the chassis or the engine.-Try to mount the MSD Ignition away from the vehicle’s antenna.-The spark plug wires must be spiral or helically wound wires and in good condition. We … I've used NGK BR6's with a MSD 7AL-2 for years, no problems (that I know of), no high mileage use though. These are the ONLY wires that will be connected to the coil. We will be connecting the MSD box to the battery later, so be sure to disconnect both cables. the other day a mechanic changed my spark plugs and i told him to gap them at .060 i picked up the mav an it runned like ****, so i get back to the mechanic and i told him " you did not gap them at .60 do you? That’s a good feeling to have,  and I highly recommend this system for anybody running a modified street vehicle or street/strip weekend machine. This will prevent unexpected voltages and spark from damaging your components and you! Here are the connected spade terminals. A factory stock distributor with a custom recurve, a Pertonix Ignitor ignition unit, and a Pertronix Flame Thrower coil supplies ignition. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor. There are a number of wires coming out of the wiring harness connected to the MSD box. If you want the MSD box to be perfectly level, you can drill the first hole and then install the first screw loosely while scribing the second hole, using a carpenters level. With the decision made, obtaining the MSD unit is as simple as visiting your local speed shop, or sending away to your not so local speed shop. The factory supplied leads will not be long enough for my application, as I plan to hide the wires on the backside of the radiator core support. The engine, with the Performer RPM package, well rev fairly easily to 6500-7000 rpm, which is dangerous territory for this hardware.

Induction for the engine is via a Holley 750cfm 4 barrel with vacuum secondaries, an Edelbrock Performer RPM intake, cam and aluminum cylinder heads, all exiting through Hedman coated shorty headers (or Hedders!) Around town drivability is much improved. Once you have all the screws started, you can now tighten all screws and bolts, as bolt alignment is now assured. The MSD wiring harness comes equipped with spade terminals, which with the provided adaptors, can be connected directly to the coil without modification. Make sure there is nothing on the other side that you can damage with the drill bit when it goes through. Here are the leads that will be going to the battery terminals. By having separate crimps, the conductor doesn’t need to be bent 180° and get squeezed between the terminal and sleeve. MSD developed a module to replace the stock HEI module in a stock HEI Distributor. They also provide a more direct connection, so I am going to cut off the spade terminals and switch over to eyelets.
