Exclamation Trailer Tail Lights

my right side brake and turn wasnt near as bright as the left side, but now i dont have anything. im not getting it at the plug at the back or the relays under the hood? also it has the 7way rv plug on it and im not getting reverse lights?? anybody have a wiring diagram on this. dont want to just start changin parts. all fuses good, relays cycle when power is applied wiring going back is good. left side brake and turn works, and all running lights including ones on right side. truck lights work fine also?????

HERE is a wiring diagram for the 7-pin plug. Maybe someone else has the diagram for the wiring under the hood.

those would be the "trailer tow backup lamp relay" and the "trailer tow battery charge relay". if they are not in there you need to put them in. they are a standard 12 volt relay, you can get them at most auto parts stores, when you buy them they will have a plastic tab on them with a hole in it to mount. cut off that tab flush with the top of the relay so it will fit under the relay cover
