Grounds, check the rear grounds
REAR TURN SIGNAL HEADACHES. (keep getting pulled over, not good)
Problem: LR turn signal flashes rapidly when headlights are off. LR turn signal flashes normally when headlights are on. Have checked all fuses,ok. Have replaced LR bulbs, new. Can't find any broken wires. Any ideas would sure be nice.

Did the problem start right after you installed the trailer connector?Might be something to do with the 4 way trailer harness I put on ? (the turn signals work fine when the headlights are on but act up when no headlights.)
