9 95hatchcx Member May 2, 2004 #1 Is the the EVAP purge control solenoid valve on the back of the intake manifold on a b18b ls motor? Does this have to be hooked up to run? I'm not sure how to convert a 1 wire 02 sensor to a 4 wire on a OBD 1 car, do you run the wires into the ecu or the wiring harness?
