What wires to keep?
Hello everyone.. Im looking at different standalone ECMs such as the FAST and the new Holley HP systems, my question is what wires do I need to keep from my TPI harness in order for things like the oil pressure switch, fuel pump, gauges ect.. to still work? Any help would be great.
