I just bought a new harness for the brake light yesterday..installed it, put the light in and turned on the lights....thay all work...but only the left brake light worked....so I swapped bulbs to see if the right would fire....no...late I went out to work on it and I move the wire a bit..and now the right works and the left doesnt???..wth?...I thought it might be loose wires in the harness but it never worked again when I moved em....I cleaned the healloutta the ground connection and made sure it was tight...but I cant seem to figure this one out?....any help would be appreciated......maybe its just a bad harness to begin with....
