Yeah but usually a jumper wire is sufficent, again not being sure where it went to was my down fall. I didn't know if it was a ground or 5v referance. I do have another question why would i be getting a o2 sensor code with one ecm but not the other? Also could that cause the car to bog out until it warms up to operating temperature it only does that with the obd2b ecu. The obd2a just idels funny but no bog.
