I need a new under hood harness. Its the one that plugs into the computer and "big round white connector" on the firewall and runs along both fenders and in front of the radiator.

I pulled a red tape with grey trim off the harness at the ECU end of the harness. I will try and attach a photo, but here is what is printed on it

ED E9TB-CE
12A581

ED= ??? I have no idea
E9= date code - 1989
T= Product line - Light Truck & Bronco I (1983-up)
B= Source code- Body and Electrical Product Division

CE= Suffix - A single letter would indicate revision and would effect compatibility, I dont know what 2 letters means

Truck is 1989 F150 XLT Lariat, regular cab, full size bed, 302fi, M5OD trans.

Too many stupid mechanics have done too many stupid things and now a real Ford mechanic is telling me the harness aint worth trying to diagnose. Gotta get an un-butchered replacement.

Please help.

Two thoughts -- and welcome to FTE

1. You might get more responses if you post in the 87-96 F150 section.
It's a pretty active group.
2. I do suspect that they will recommend that you try a junkyard or look for a donor vehicle. Harnesses are generally manufacturer only parts, and Ford probably doesn't have any of that vintage. But, who knows, maybe somebody has them.

Good Luck,

I posted it there, but i need to understand thus coding, most used harnesses won't still have the part number so I'll have to match it by feature. Having an impossible time finding this, or being sure it's right one.

Your right ford doesn't make it anymore
