100/90w HD wire harness and 100w high beams
HD wire harness from LMC, looks like something form Aliexpress but its all there and the harness is just long enough to run it in the factory position. pretty painless install, I also installed some 100 watt HELLA bulbs. I've heard goods and bads about the Korean Hellas for $2.50ea I wont complain but after a couple of hours of use they are still burning. I do need to adjust the headlights they are way high and I didn't notice until I installed the new high bulbs.
I fastened the harness to the main hot cable in the fuse panel, routed the relays beside the fuse panel and ran the wires along side the factory harness. zip ties, electrical tape and ribbed conduit. The harness had individual grounds for each headlight plug, I mounted them behind the washer fluid jug on the driver side and below the air box on the passenger side. I covered each headlight lead with ribbed conduit. the only thing that you can tell is different is the relays on the fuse box and the loud click they make when you turn the lights on, or swap between low and high. The relays are switched by the factory High low connectors on the factory harness they plug in where the Headlight bulbs plug in.
