The harness is a "hafta".
AutoPal's E-Code are big improvement over stock and are inexpensive.
$74. Yes it does include everything except maybe some generic instructions. this should help:
Cruiser’s Headlight Upgrade Harness Instructions
Absolutely plug and play. Remove grille and headlamp bulbs. I fed my harnesses from the Nothing 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.
Question... With the eautoworks wire loom upgrade, can I run 100watt bulbs? I can get some nokya's or luminics that I think are 80/100, I run the luminics in my Honda and they put out better light than my old jeep did with high beams and 4 of slim light (driving lights)
Sylvania Silverstar Ultras are a good solution if you want plug and play... They gave me a tremendous increase in light output on both high and low and provide a nice white light.
Hey Cruiser, Hi from up the road :wave1:. How hard was it to switch out the harness ? I could see myself doing the switch and then "mysteriously" not being able to start my Jeep.
I used to run Silverstars and got a good amount of light out of them but they burn out quite quickly compared to other solutions that don't cost much more.
