hi, my buddy put slt (single bulb) lights in his 02 3500 sport (two bulbs). The high beam light will not shut off and the lights are dim. Is there a harness or relay to fix this? Thanx Tom

 

Look at the schematic and make the needed changes. The lights are not wired the same.

 

There is a harness you can buy

 

hi, where can I get that harness? Thanx, Tom

 

I am thinking go to e-bay and search "Spec D" (from photos). But I am guessing. That's where I would start I think.

 

well that harness is for running the after market single bulb headlights on sports. but when I got my lights, they sent a harness that goes 2 from the headlight into 1 on the truck, so I am sure the harness is out there somewhere.

If you just want to see the wiring/harness portion, skip to 7:00. The guy explains it all very well.
