hooked up trailer to the wires under bumper...I see 6 wires and only used 4 of them....every thing is fkd up....light on and apply brakes everything goes out...left signal on and right trailer light lights up and visa versa..only one (filament) part of bulb is being used....all colors match...two wires not being used...light blue and cant remember the other one...any ideas?

 

ok... this thread can be deleted....its called letting a friend borrow your trailer and they don't tell you that they broke the ground pin in the pigtail....have a wonderful week!
