I have a car with the orange box set-up. It has 4 pins and the harness has 5 pins. The problem I am having is the car will only run if the two wires on the Ballast are jumped together. Could the difference from harness to ecu cause this? The fuse links are all good. It only appears to be on the run side of the ignition. Can I get a 4 -pin harness from somewhere? Thanks Tod
