I have a 1983 rx7, just recently bought a 6a msd box and 2 blaster 2 coils. What i need to know does anyone have a detailed schematic for hooking this up?? With the 6a box i can only run one coil and the leading plugs right?? then just leave the stock ignition for the trailing?? Please need help ASAP....

This is my latest engine pic. With the MSD, very easy.

Big Red + and Big Black - to Battery

Smaller red to a wire that turns on with a key switched on.

White is not used

Orange is positive in the leading coil and Black is negative. This is in a wire loom by itself. There should be no wires attached to the coil. Take off your factory wires for the leading.

Violet and Green which is on a plug goes to where the leading igniter is at. The wires here are hooked opposite. Violet of the MSD goes to the green in the distributor. MSD Green goes to the violet of the distributor. You have a couple of options. Take off igniter, put some spade terminals and trim them to fit in the slots.
Gut the igniter or cut off the distributor terminal for leading and crimp them together.

My RX-3 wagon is running like a fuel injected car with the MSD. Hope this helps, if you have questions feel free to contact me.

 

Im sorry..but does anyone use force ignition boxes...when i hit rev limiter it doesn't sound the same as when my freinds 1st gen hits rev limiter..he uses msd's boxes? Anyone know why?
