Cruiser’s Headlight Upgrade Harness Instructions
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.

I've only used the eautoworks/putco/lmc harness with the six pins. Had no trouble even with 90/100 bulbs.

I never had to upgrade my relays. Mine's been on a couple of years on the "insert manufacturing company here" relays that came with the lmc harness.
