I need to get a new wiring harness for my 74 260z. I was also wondering if any of the wiring harness from the other z models would fit a 260z? If so what year?
Nissan is actually very good about still offering parts for the early Z cars. I would check the price at your local Nissan parts department. It won't be cheap but getting a used one could be a lot more expensive in the long run.
I'd say you're most likely going to have to rewire that one yourself unless you can find one on the WEB somewhere from a salvage yard or something.
