So I put an s5 motor in an s4 car. I know I need to change the connector to the altenator on the drivers side. I changed the pressure sensor and the hot wire mass air sensor or whatever. Whats all involved with the body harness that plugs into the ecu? Do they make a connector I can buy that has the s4 connector on 1 end and the s5 connector on the other so I can simply plug it into the s4 body harness and s5 ecu?
