To make a long story short, The Harness I have on the 98.5 from the front driverside to the back that does trailer controls lights turn signal and what not is all hacked up. Where could I find a complete harnessfrom the fender back?

 

Salvage yard if you are friendly with them. Pull a Part yards around the country frequently have applicable units in inventory. It might still be avaliable from dealer but would be expensive. If not in big hurry(like a month) I can probablly supply one from local yard.
