I need to know if anyone has done the MSD 6AL-2 ignition installation on a 1985 12-A with electronic distributor and hopefully wanted to share pictures or a diagram for the wiring of this system on this type of engine.
thanks!

 

i have one too but havnt put it on. just being lazy with wiring and finding a place for the box. go to Mazspeed's First Generation Rx-7 Club Page theres pics and instructions

 

check out scott bakers sand rail page, he has a really good write up on whats required to make it work.

MSD 6A direct fire Ignition for Mazda RX-7 Rotary Engine - Dr. Scott M. Baker

 

This is what MSD sent me, I don't use a trailing MSD. Been working fine for 6 months. MSD6.

If you call them, they have excellent customer service and will send you the exact diagram you need.

Here's the guy I got my info from, second image.

 

Excellent!!
thank you guys for the info I'll get back to work tomorrow on the install and let you know how it work.......

 

I followed scott bakers writeup also to the T, and havent had a problem in 3 yrs since I installed it. Juantii pm me and I can send you pics of my install on how I installed 4 coils, 2 for the msd box and 2 for factory wiring in case msd box fails, so you dont get left stranded on the side of the road.

 

Just answered my questions!!!!!!! ty

 

so what way is better two boxes and two coils or one box and 3 coils ?? pros and cons for both ??

 

Here 4 years after you looking for the same answer haha..

 

3 coils and one box is the only way to go. Anything else just cost more and clutters up the engine bay.
