The VP has independent power that needs to be supplied by a simple relay. Theses relays have 4 posts (some have 5, if so disregard post 87a)

00-02 engines need to retain the WHITE/ORANE wire from the harness. This gives a speed signal to the ECM so it will fuel.

Looking at the FORD PCM from the TOP you will see the chassis plug on the far right. The the firewall end of the plug will have Gray wire with a black tracer. Attach the White/orange wire from the dodge to this wire. DO NOT CUT THE GRAY/BACK WIRE!!!!! SOLDER ONLY

Also, there is a large black Cable that pops out of the engine harness near the VP plug. Its the alternator charge cable. Attach to a hot battery side. Near the alternator you will find a similar cable with a brown tracer. Ground it to the frame
