David Irwins plug and play harnesses are the best around. Make sure to get the parking light harness too, as that is the one that usually melts the fuse block. I dealt with David directly. I do have a funny story. After putting the headlight harness in, I didn't see a difference. I pulled up to a wall and switched from bright to dim and back again. One headlight was on brights, the other was on low beam. When Dave put it together he switched the wires on the left side. Simple fix by swapping the wires around and as good as new. Told Dave after I fixed it and he was really apologetic. Thanked me for not throwing a fit about it. I just thought it was funny. The thousands he has made up, I'm sure there might be a few that had the wires crossed. Headlight harness- all under the hood work Parking light harness-- one wire fished through the firewall and snaked though the dash to the steering column bolts.
