I just finished a motor swap for a friend. The car is a 92 civic vx. The swap came out of a 97 gsr which is obdii. I chopped the harness at the ecu and switched the plugs. I am using the gsr harness on the motor and the vx to the computer. My only problem is the primary o2 sensor check engine light. I know that the vx is a 5 wire. I want to just hard wire the o2 but from what I can tell is that only one of wires goes to the ecu. One goes to 12v swithed. The other 2? please help
