Hello everyone I recently bought a b18c4 complete swap. Everything fits into ek but the engine was mounted on eg previously. I have an engine harness that was been modified by the guy because the engine is from an ukdm car rhd and the guy mounted it on a eudm eg and had to lenghten some wires. However i didnt quite understood how he did put an obd2a engine harness on an obd1 car. Anyway i was looking for someone to tell me what engine harness to use original or not doesnt matter. Ive read that you can use an obd2b ek4 harness because my car is a facelift but they are quite rare, pricy and impossible to find. Anyone has some sugestions?

 

What's your goal with the car? If it's not to keep it stock and/or run the original ecu your best bet is to get an aftermarket loom form Rywire, et al. Even a 'budget' replacement loom is a great investment over putting work into a 25 year old oem one that's been plugged and unplugged god knows how many times. Probably cheaper than trying to find a used one for your facelift chassis too.
