quick story is, I have an engine harness and PE computer only, transplanted in a 79 capri. Car runs and drives, but as I roll in, I get a bog. I want to eliminate any electrical or wiring, and I noticed, I don't have the premium fuel switch or the wiring. If I'm reading the threads right, grounding pin 30 coming out of the ecm will keep the car in premium mode? any help is appreciated. I just bought a set of switches and wiring from MIKESSVO86, but I have zero dash wiring, or any wiring sending it back to the ecm. thank you all!
