i didn't have trailer tail light hook ups on my truck so i bought the T connector (the ones that don't require splicing just plug and go) and now i tried the lights and they are extremely dim and only a few of them even turn on. help!
It seems with trailer lights it usually is the ground connections. Check all of them. Spray some WD-40 in the connector and wiggle it around
i greased the connections and it still didn't work then just started driving and i guess the hitch made a ground connection and now it works like a charm.
