180sx Wiring Harness - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a 1990 180sx with a ca18det. I sent Wiring Specialties an email about buying one of there pre built harnesses but I'm being told that since I have a RHD there is nothing they can do. I even asked if I can't send them my factory harness so they can change out the connections and reloom it. And I got told they can't help me. Does anyone have any suggestions? If I buy the 240sx swap harness for the ca18 can I make it work?

What are you trying to do?

I originally wanted to just replace the harness. Car is 25 years old and I wanted to eliminate future electrical issues. And the guy who had the car in Japan didn't wrap the aftermarket turbo manifold so the heat kinda took its toll on some of the harness. I see Wiring Specialties has a sr20 harness for the rhd cars. I guess the ca18 is the oddball.

Your best bet would be to buy a brand new CA18DET wiring harness from Wiring Specialties then reverse engineer it to plug up to your car. Which means swap the 180sx body plugs off of the original harness and wire them onto the 240sx CA18 Wiring Specialties harness.

Not hard at all but time consuming for sure, and not recommended if you are not familiar with wiring.
