This new wire harness plugs directly into your existing headlight wire harness. It uses 2 relays to directly connect the headlights to the battery. The headlights are brighter, and the dash lights are brighter.
This is because the stock factory wire harness draws power from the battery, to the fuse box, up to the headlight switch, out to the headlights. That's a lot of old connections and wires. You do not need to cut any wires.
Price is 70.00, and the wrap may be yellow or black.
