Read post #75. If I could go back, I would have double/triple checked everything. I have a short somewhere in the wiring harness that still needs to be repaired. The biggest thing is to try and figure out why the fusible link went bad in the first place. Good luck and the CC crew is very helpful.

That looks to be the option. I've got the 1988 wiring e-book website and will use it as a guide when rebuilding. I need to read up on what I need to rewire and what can be removed. All this electrical stuff makes me miss building classic mustangs with my Dad.

Does anyone have a lead on a complete wiring harness? My searches have come up empty.

Can you send me a few pictures?

this is the driver side of the truck. It appears that the orange wires got burned to a splice. I haven't cut into the orange wire to see how far past the splice the damage traveled.

The harness comes out that hole and runs between the radiator and auto tranny cooler. Then up the fender and under the washer fluid, until it plugs into the firewall.

No it isn't.

The damage did move down harness. Is that what you mean by "slicing into the harness"?

It looks the same.

I'm gonna drink a cold one tonight and start on the diagnostic work tomorrow. I'll post pictures and seek more assistance.

What's my best plan of action? Get a 87 harness with everything attached and get to work? Would the 88 harness work? Or is it easier to run all new wires?

Yeah. A CC member said he had a complete harness out of an 88 including computer. I asked if he had the B+ relays, starter relay, fusible links, and connectors. I'm waiting on his answer. Would an 88 harness work?

It appears that the damaged wiring went as far as the middle of the radiator and towards possibly splice E on the firewall.

I appears that the following are damaged: B+ latch relays (4) C106 C107 C104 C109 C103 C105 C335

Do you have the starter relay and fusible links, as well as, the B+ relays?
