Just after someone to check my wiring really, pretty sure it's ok but never hurts to get a second set of eyes.

I have the MSD 6A and GM twin coil on the leading and two AEM smart coils on the trailing. AFAIK the MSD doesn't need to go through a relay like the power feed on the smart coils, it takes its own switched signal to do that. Relay has a 30A fuse.

 

What ECU? Does the GM coil have an internal igniter?

 

Apexi PFC.

The GM coil is hooked up to an MSD CDI box. MSD just says to feed the box either a points trigger or signal from the igniter, am I running the risk of frying my PFC by taking the igniter out of the circuit?

 

The PFC is not going to fire the MSD. Igniter must be in place to trigger MSD. The AEM smart coils have internal igniters.

 

Aw crap, back to the drawing board.

Cheers guys, saved me a headache there.
