bought 9004 hb1 leds. Thought they were plug and play wrong wired like 9007 with center ground that’s when the fun started. Jumped from bat lihhts work fine. After trying the bulbs wired with the wrong ground the truck wiring went to hell. Have continuity from ground bat t to all turn and marker wires.right hl grnd and hi left lo and hi, with multi function switch and headlight switch out. Checked multi with meter per haynes manual good. Headlight switch power in on numb er 2 term powers one, should’t it power number six headlight switch output going to multi 19 .in the connector 20’s hot. When i purchased trk front end was melted litghts rigged fuses jumped or wired did it have fog lights, dlr ? Can’t find wiring digraim with fuses for right and left headlights in power dist, 15a slot one and two pk-yl. Rd-yl help
update could’t log in for a while, found photo online of a pmc that’s a dead ringer for mine but for a 3500 got wiring daigram it makes sense but weird. Also how do you test headlight swit h, some wires to it have been to hot
everyone been looking in the haynes manual, one conciders himself to be an electrical eng’r went home with his tale draging, i was glad because he wanted to undo my flatb red wiring
open to all ideas

 

Electrical eng'r disconected headac lights ground to one side, everything now works

 

I had the same issue with HID lights not working. Apparently the dodges need a direct wire. I had to get this relay kit for mine.

Good luck the pins suck but once you get it in. You can see so much better.
