rb20det engine harness to chassis wiring, need help

[Empire087]

I have my wires coming out of my engine harness that are supposed to go to the chassis. However i only have a bundle of wires. Does anyone have a diagram or knowledge on which wire corresponds to eachother rb to s13 chassis?

Thanks,

Ok so i have a yellow wire coming from my rb harness, a small bundle of 3 wires all black/white, and a black wire. Any idea what wires these go to? None of the guides specify these wires. So im kinda stumped.

have you tried everything ? i see alot of diagrams and ECU diagrams for the RB it takes awhile but you might find what you need

Also if its a harness thats been molested it might be something the last owner did or had other aftermarket stuff. if it becomes a major headache i would just maybe sell it and get your self a new harness from wiring specialties. way worth it and its just a plug and play.
