I have a 1989 Nissan 240sx. Somehow the fan caught a hold of the wiring harness and tore all the wires. any idea how much it's going to cost?
Buying a wiring harness will be prohibitive, and even transplanting one from a wrecking yard can be expensive. The harness can be repaired by splicing in pieces of wire where wire is missing and splicing together damaged pieces of wire. It is tedious but not particularly time consuming - I spliced in a section of harness after an engine fire in about 2 hours, working slowly.
Depending on how many wires were damaged and need repaired, I wouldn't recommend a repair unless you can solder them and heat shrink them. And you would want to stagger the joints so they are not all in the same place. Getting a used wiring harness shouldn't cost much. Probably the same as getting all the tools necessary to repair them. (if you don't already have them.) then all you have to do is run the new one along the old one and unplug connectors one at a time.
