I think on a different thread it was said the wiring connector pins are the same for both, you just have to unpin them from the composite light plastic sockets, and repin them in the quad light plastic sockets. A bulb doesnt care which end of the prongs is power and which is ground. Each lightbulb socket is going to have a black wire for chassis ground, and a feed wire. Tan feed is low beam, and a light green feed is high beam.
I believe trucks with DRLs (daytime running lights) have an additional tan feed wire along with the light green going to the high beam to feed a seperate low bright DRL filament in the high beam. If your truck has DRLs i think 1996 on up you just wont be able to hook up that extra tan wire into the high beam plug since the quad light high beams only have 2 prongs and not 3 like a DRL high beam bulb has. Just cap and stow that extra tan wire on each high beam in case you decide to go back to composite lenses. I would just use shrink tubing on its connector pin and stuff it back into the harness
