would anyone know if this white main harness for the rb25det is the same as the main harness plug from the ka motor? If not would anyone know where I might be able to get one from? My friend dog took a bite out of mine so now I have to find a new one. please help. also If Mack from Mckinney read this, this is the plug I need, do you have any at your shop? thanks for all the info I received from you guys. a picture of it is link below

If you have an S14, I believe its pretty much the same, just gotta re pin it to work as the RB one...I never really use that plug though, I always get rid of it all together.

My harness had that plug cut off right at the main bundle. So I never had one to begin with. I just took a digital meter and traced it back to the ECU plug and labeled it. Took some time but double/triple check it since it would suck if you installed it in the car and it doesn't run and you have to retrace everything.

thank you for your help. well I was gonna repin the harness but now I think I'm just gonna send it off to mckinney. only bad thing is it's gonna take 3 weeks. I don't have that long of a time frame. Anyone on here might be able to help me out? Jon, Kamin, anyone? I'll pay the same price as mckinney. just need to do it in no more than 2 weeks. If you can help me then please email me at [email protected].. thanks for the help.

I have never sat down and wired an S14 so I dont really feel confident that I could do it without the car.

if the plugs are the same just unplug one wire at a time from the rb harness and put it into the same pin on the KA plug.

the problem is the pinouts are different. meaning one wire on the KA side is in a totally different spot on the RB side. you have to repin the entire thing.
