MSD 6a Install instructions???
Can someone please post instructions on how to install this Amp? I just got this not to long ago, and can't find any instructions on how to actually install it. I search for MSD and got no help.
If someone can post which wire goes where or if you have a picture, that would be awsome.
Thanks a lot.

Everyone that I have seen with MSD's install has three of them. I would guess to balance everything. Also there is a wiring mess when they are installed. The Twin power is by far cleaner and easier. Also havn't heard of the twin power burning out, common on msd's.
Thats enough of my 2cents so I know a guy who has the tri power thing installed on his car I will see if I cant get him to post how its wired on here.

I can. I have one on the leading coil and it's made the car much more enjoyable to drive, especially on the low end. I'll have to find the diagram but I can tell you that I made the coil connections near the FD leading coil and not at the stock amplifier location because Mazda uses some resistance wire in their ignition harness. You can connect power right at the one of the main power box distribution terminals and the ground on or near the main ground lug. I'll get the rest of the info and post it.
It has been the experience of many, including myself, that you don't need three boxes; just one on the leading, since it does most of the work. Anything after that will produce diminishing returns. If you can get the leading mixture lit, you've got 95% of the battle won. For that reason, an MSD or other multistrike will produce better results and driveability than a single strike ignition--especially when the mixture gets ragged. The reasons for this are based in physics and the laws of probability and confirmed by 23+ years of my own experience and testing; not hearsay.
I have also found that gains can be realized by using unshrouded type spark plugs (again, in the leading) and adding substantial timing under LIGHT LOADS and at lower RPM. This coupled, with an MSD, can really wake up the bottom of the power curve on these motors. The trailing, so long as it's firing, shouldn't need much attention--just be sure to get the right heat range of plug for your conditions. A close examination of the plugs can tell you alot about what is going on with the motor, fuel and ignition. Be sure to have them examined by someone that really can read them if you're not familiar with this.

I just got done with installing one (and a T-II primary coil) and can say that it runs so much smoother above 12 psi. You definitely don't need 3 of them.
This should help: http://www.msdignition.com/pdf/6%20series/pdf24.pdf
You'll have to snip the wires to the coil to insert the MSD. The Black/Red wire is (+) and the Yellow/Blue wire is (-)
The MSD Black wire connects to the coil side Yellow/Blue.
The MSD White wire connects to the ignitor side Yellow/Blue.
The MSD Orange wire connects to the coil side Black/Red.
The MSD Red wire connects to the ignitor side Black/Red.
Ground the big black MSD wire.
Hook the Big Red MSD wire, through a 10 amp fuse, to the battery. It doesn't have to be a switched power source.
For what it's worth, here's a pic of the FD primary coil that's burried underneath the UIM so you know what you'll have to cut.
The rest is just finding a good place to mount it. If you have to add wire to the harness make sure it's a decent gauge wire.
Hope that helps.
Dave

install is pretty easy.
Exactly how Dave said it.
Basically, you power and GND the box (also with a switched 12V). Then you send the leading signal from the ignitor to the box and send the box output to the the coil.
One works great for me @ 17psi.

also, with the 6AL, is the rev limiter setting needed or is it best to leave it on the "No Limit" Setting. I'm using a stock ECU. I can't imagine why the 6AL would disable any stock rev limiting functions.

Gordon - using two MSD amps firing off trailing signals sounds like a great way to run a strong ZERO split ignition...but, you say you ran "almost no" trailing 
can you explain a little more?
also since MSD fire 3 rapid fire shots below 3k...firing 3 rapid fire shots, in the leading and trailing holes at the same time seems like it will give poor performance below 3k. Am I missing something here?
I assume you ran two Amps with two leading (type) coils.

The rev-limiting function of the 6AL cannot be used without a custom setup that disables the trailing coils when the limiter is active (since they will continue to fire via the stock ignitor). Leave it disabled.

I very much agree, I'm just running a 6A on my leading and when i switched to a two post MSD motorcycle coil and 2 blaster SS coils I noticed a world of difference. Low RPM driveability went WAY up. Power delivery was very smooth with ni breakup (of course I didn't have breakup with RX7 coils and the 6A.

well good luck getting it, summit has had it backordered for some time. Maybe everyone's done working on their bikes now and summit can restock.
the blaster SS's are MSD-8207
the dual post coil is MSD-8204
edit: actually it appears summit has them in stock. However I found the dual post cheaper at: http://www.mpsracing.com/products/MSD/ig02e.asp I got mine from them, they shipped it very quickly. I was pleasantly suprisec. I jsut wish it would have come with nice new MSD spark plug boots and ring terminals like the blaster SS's did.
I have my coils relocated so making a bracket to accept the odd sized dual post was much easier. Good luck.

what about gm dual post coils like on firebirds etc. i mean they are used as a wastespark system but on an fd it wouldnt matter. P/N is MSD-8224 and is in stock at summit. luckily i live about...6 miles from summit racing HQ here in Ohio

I knew it was only a matter of time before this coil was brought up. i don't knwo of anyone that has tried it. The stats are not as good as the motorcycle coil, but it's half the price.
A board member that was putting down good power put me onto the 8204. I tried and and love it. If you want a proven dual post then get it. If you want to experiment and maybe find a cheaper route go for the 8224 and share your results.
