Finalizing wiring for my 5.0L. 5.0L is from a 1990 Town Car. I've integrated wiring harnesses from the donor vehicle and my 87 BII. I used factory wiring charts to complete.
I have also reviewed the Ford Motor Sport Multiport EFI Engine Management Harness instructions. It makes NO reference to the type/model of ECM being used.
I also reviewed the Painless Wiring! Wire Harness Installation Instructions for Installing the Ford 5.0L 1986-93 Wiring Harness. Their instructions DO reference using the A9P ECM with an automatic transmission.
Painless Wiring! has a diagram showing Red/Blue wire from ECM Pin 30 going straight to the starter solenoid/relay. They claim failing to do so can damage the ECM. This is different from my Town Car wiring.
A lot of background to get to this question:
If you have a 5.0L with an automatic transmission and are using a A9P ECM, how did you wire pin 30?
Thanks!
