4 Prong Trailer Wiring. It is easier than you think. I have one on my trailblazer because it is five wire and my boat trailer is four wire.
It plugs right into the harness on the tailights and you snake the wiring underneath the bed. There will be two brown the wire you maybe talking about could posibly be for the trailer brake controller, which you have to buy serperate i'm not to sure how much it will run. The fuse panel has a designated fuse and has power but no power is getting to the rear of the vehicle?
The fourth prong is there for a reason.
If your vehicle is not equipped with a working trailer wiring harness, there are a number of different solutions to provide the perfect fit for.
You will need the electrician to. The trailer, on the other hand, in North American, uses the same bulb (and one red lens) for *both* the stop light and the turn signal. hence the need for a wiring. So my question is where should this white wire be connected to, the green screw or should I connect it once again to the.
