Putco heavy-duty 9006/9012 harness with relay bypasses the headlight switch by pulling power directly from the battery to increase light output while allowing use of the factory switch. Rated for high temperatures and equipped with hard-insulated plugs, it’s not intended for vehicles with DRLs. The harness installs to replace original plugs and supports higher-wattage bulb setups.
