I am doing a b18c1 swap into my 90 CRX dx and i am having some trouble. This swap is notorious for its wiring so i need help figuring out which wires i need to cut and splice to make the OBD 1 engine harness fit my OBD 0 car harness. Nobody does this swap into a rex THEMSELVES, so its hard to find information. I dont have the money to pay somebody to do it either...Can anyone help?
Thanks.

 

Why don't you use the B18C harness instead of the one you have now?

 

Buy an OBD0-OOBD1 harness from somebody. Search Honda-tech for vendors if no-one on here has them.
