2000 Sterling L9500 rear wiring diagram needed

Had this truck stretched and the outfit that did it, wired it wrong and now we cannot figure out the proper wires for turns and brakes. Have wires seeming to feed back, as I know how to use a wire tester and see what one are hot and which ones aren't, but this isn't that simple unfortunately.

Ideally if someone knows what color of wire is for RT, LT, B & RL, would really appreciate it or any other suggestions.

Thanks

 

Lol, no, not yet. Have had other birthday's to attend, so maybe next weekend weather depending. Any help would be most appreciated.

 

all, yes. thanks
