Product Questions


I am putting my 302 ho efi out of a 93 f150 into a ratrod project. Is this harness what I need to make the engine run? And what other harness will I need if any for accessories. Thanks

Asked by: Jimmyrat
Yes, this harness is what you need. You'll also need a PCM. Any accessory harness(es) will be dependent on what accessories you're running.

My harness (ford racing) has a fuse box, and when the ignition is  switched on the green lights cycle in the fuse box, now the one listed a/c has no power and the fuel pump does not cycle and no spark. what is the a/c mean , car has no ac installed ???

Asked by: BIGEZ
Just because your car doesn't have A/C, doesn't mean that others who install this wiring harness won't need a circuit to power air conditioning. That being said, it sounds like you have big wiring problems. If this has been going on since you installed the harness, check all of your connections to make sure they're wired right and good connections.
