Factory 1980s GM wiring routes all of the headlight power directly through the dashboard switch, causing a massive voltage drop that results in dim, yellowed headlights and overheated switches. This relay modification bypasses the dash switch for power, pulling crisp, full voltage straight from the battery source to your lamps. You will notice an immediate, drastic increase in nighttime visibility and headlight brightness, all while protecting your interior dash switch from burning out.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCondition Details:\u003c\/b\u003e This original GM copper core harness is in excellent functional condition.
