This article will cover the three components mentioned first. IAA-unit:This unit consists mainly […]
General:Unfortunately the rubber used for sealing the contacts to the harness is prone to crack after years of use in the hot environment of the engine bay. When it cracks, the moisture from the air can enter the contact and cause it to corrode. Of course the best thing is to replace the old harness […]
