I have a 98 Ram 1500 4x4 Sport and it had the plug under the dash for the electric brake controller. 4 wire. In the engine compartment there is a Trailer fuse relay, (Not sure if it is blown and do not know how to test it.).
I installed the brake controller and plugged in the trailer connection without hitching it to the truck. I have everything except the Electric brakes. It is not connecting to the trailer. Does it have to be hitched?
When i got underneath it I found out the previous owner had U-Haul do their hack job on it. After I unraveled a roll of electrical tape I saw that the white and black wires were not connected. They were just folded over in the electrical tape.
I need to know the following:
1. Does the trailer have to be grounded to the truck through the ball and receiver of the truck?
2. If the trailer relay fuse is blown will that affect the electric brakes? If it is, then how do I test it?
3. Do the black and white wires have to be connected? I thought they were for charging the trailer while it is connected to the truck.
4. Can I run the trailer brake wire straight to the controller or where do I find the connecting wire if I cannot do that, (Assuming it is not connected at this time.).
Thanks all for your help. I really hate wiring, but am capable. What I really hate is that someone paid U-Haul to make this ridiculous mess under the truck. any assistance will be greatly appreciated.
