I am finishing splicing together a new centech wiring harness and an EFI wiring harness from a '91 mustang 5.0 and I need to know what the blue "ignition pwr" wire from the centech harness needs to be attached to. I also have an MSD ignition.

Also, where do the white "coil" wire and purple "start" wire tie in to this EFI wiring? The other purple "start" coming in to the engine compartment is tied in to the S post on the solenoid.

I have Centech and RJM harness and hook up like the following:

EFI Harness A ORANGE --> Centech BLUE
EFI Harness B WHITE --> Centech ORANGE
EFI Harness C BLUE --> Centech BLUE

White coil does not hook up to anything. Just tape it off.

Purple goes to NSS Neutral safety switch

I have the stock mustang wiring harness so the RJM wire colors don't mean anything to me. Anybody know what the Centech blue "ign pwr" and violet off of the 3 pin connector need to be hooked to in the mustang harness?
