You open your tailgate...undo the screws on the inside part of the bed, slide the tails out....the rest depends on if u have the new wiring harness or not

if u've got the wiring harness, go under the bed, there should be 3 sets of plugs. Unplug one for each tail light, and plug the new stuff in.

what he said and if you don't have the harness you can mod you existing ones to fit the new tails. I don't know how to do it but i think a few people on this site have done it or atleast know how

i dont have the harness, but the 99 to the 04 harness is different, theres 5 wires to the 04 harness and 7 wires to the 99 harness, so i dont know if i can splice wires from the new harness to the mine or not
