Ok I will email them, The descrip for the wire set I was looking at says.
This subharness will add wires for your VTEC Solenoid, VTEC Oil Pressure Switch, 2nd Oxygen Sensor and Knock Sensor to your 88-91 CRX HF/Si.
This is ideal for a b16a swap.
So if I plug the b16 ecu into the stock harness it will run?
