Either that or one from lmc truck. They are probably both made from the same company. We pay the extra price for the name.
Go to the junkyard and grab some relays out of a older honda accord or madza for some spares, you never know of you'll need them.

Actually, if you scrape the grounding points down to bare metal and mount the relays so moisture can't get in them, you'll likely never have a relay failure.

Ok and I have seen these harnesses before but was always tripping on how you only use one headlight plug

cruiser54

You okay with that now?

Kris smith

Not really but if it works. I'd like to get the proper output from my lights

The Putco is fine. I've installed numerous harnesses from them.

Cruiser’s Headlight Upgrade Harness Instructions


It's easy to install a supplemental headlight harness.

From the factory, the voltage to the headlight bulbs travels from the battery, inside the cabin, to the headlamp switch, and then back out to the lamps via undersized wire. It's not uncommon to find only 10.5 volts at the lamps.

The supplemental harness is installed so that it provides battery voltage to the lamps and is just triggered by the factory wiring. The result is about 30% brighter headlamps and headlight switches that don't melt and burn out.



Absolutely plug and play. Remove grille and headlamp bulbs. I fed my harnesses from the passenger side starting between the battery and the back of the headlamp housing, over to the driver side. Plug the driver side bulb into the new harness. Attach the new harness's ground wire under one of the small bolts on the radiator support after scraping the paint off under it. Attach the harness to the existing harness behind the grille working toward the passenger side. . Plug the new harness plug into passenger headlamp. Plug original headlamp plug into receptacle on new harness. Attach the ground for the passenger side just like you did the driver side under a radiator support bolt. Attach relays with provided bracket on the passenger side inner fender. Connect power wires to battery.

After the conversion, that plug is only used as a 'trigger' for the relay, not to power the headlights.
It's a good idea to cover the unused plug also.
