I want to post this in case anyone else is having a problem trying to wire their trailer. I rewired the complete trailer but was having problems so I took it to a trailer/camper dealership. There were two guys working for two hours on my trailer. The problem was this, my 1962 Sterling boat trailer breaks at the yoke and as soon as they attached ground to the rear of the yoke, it worked just fine. If you trailer breaks make sure that your ground is on the rear of the yoke!! OH and the two guys for two hours, they only charged me $20.00 dollars. Whew, I was getting worried as time was passing by.
