I recently purchased a OBD0 Vtec harness from Rywire. I went to install it tonight and had a few questions. The two wires A8 (Vtec solenoid) and B19 (Knock Sensor) simply plugged into open spots on the harness. The other two wires B5 (Vtec oil pressure) and C8 (2nd oxygen sensor) have wires currently in the harness. My question is do I simply remove these wires and install the new ones?
