Hello everyone, I drive an '08 frontier kc 2.5. 10k hids with billet chrome grill, chrome running boards along with chrome mirror covers and door handles, white LEDs all around (dome, cargo lights, license plate, reverse light). Rockford fosgate sound system. Question: I'm trying to install an led tailgate light bar, but I need to hook it up to a 4 pin connector, I know there is one under my bed that came with the truck, would I need to just buy the trailer lighting harness to get it to work without a malfunction??
