  • Made the tailgate light install easy.
Used this item to wire an LED tailgate gate light set. The adapter plug made the job super easy and eliminated the need to direct wire to the truck light assembly or the trailer hitch plug. This adapter fits before the trailer hitch output and creats a secondary cable that wires directly to the new lights without have to splice every OEM wire. Cables assembly can easily be tucked away and not see or exposed. ... show more
