2008 express van trailer lights
ok so i have a 2008 1500 express van. I've been using the factory trailer light adapter since i got it. last month i went to bring a DJ trailer back to the warehouse and the lights didnt work. at first i thought it was the trailer, but after hooking it up the my mountaineer, the lights worked. i found another light hook-up further up the chassis, but had no luck with that either. i did some thinks with the wiring when i put in the subs and the new taillights , but it still worked after i did these things. any help?
