Hey guys,
I've hit a bit of a snag in the wiring on my '98 2wd 289 swap. When I pulled the 4.0L OHV out I cut the 42 pin connector (C124) on the engine harness because most of the wires there I don't need. Now naturally, being a Ford, half of the wires in the harness aren't the same colour as the manual says they are. So far I've got my HEI wired up and the oil pressure and coolant temp sensors plugged in. Now my issue is that I can't find the wire that the starter relay is supposed to power to go to the solenoid, nor can I get power to flow properly through the relay. Can anyone tell me if the relay is hot all the time with the ground being switched, or is it the conventional switched 12 volt? Also, I sold the PCM with the motor a few days ago because I was told I did not need it because it is the end of the line for the wires to the gauges I need. Can anyone confirm to me without a doubt that I don't need it?
In short:
1: Starter relay wiring help.
2: Is the PCM required for a carbed swap for the gauges to work?
Thanks in advance for your help and advice.
