I have a 2000 LS engine harness. I also have a 1999 gsr with a 2001 b18c1 motor (block and head are 2001, everything else about the motor is 1998).

Will I be able to use the 2000 LS harness with this motor?

I also found other harnesses for a b18c1.
32110-P72-A03 = stock 1999 b18c1 harness. (OBD-2)
32110-P72-A01 = stock 96 b18c1 harness. (OVD-1?)

 

LS harness with a GSR? You do realize you're not going to have the vtec solenoid, knock sensor or secondaries on the LS harness right?

 

yes. i do realize.. i was gonna run new wires for the vtec and knock sensors. but is everything else compatible.
