I got a 94 honda civic dx and I am swapping out my d15b7 and putting in a JDM b16a Sir2 I don't know what car it came out of from Japan, but I think it is a Del Sol because I got a p30 ECU.. Anyways my question is will the vtec work after I plug in the b16a Sir2 engine harness into my stock wiring. It should right because I have the right ECU unless my stock harness is missing a few important wires...If anyone knows please help me out....

unless you are changing the wiring harness from inside the cabin too, then no your vtec will not work unless you run 4 other wires from the motor to the ecu.

Anyone know what four colored wires are the vtec operation wires?

Thanx
