Need help wiring for 7 pin trailer connector. Now have the standard 4 pin.

Go to you local U-Haul Store...they are the best and the cheapest for wiring!

When I bought my 02 it was wired for 4 pin. I went to my local auto parts supply and they sold me a 7 pin plug made by Hidden Hitch that has the 4 pin plug you just plug into your exsisting wiring and 2 wires (1 black 1 blue) about 20ft long. The black wire goes to your battery and the blue is for your brake controller. It's easy to do.

Good Luck!

I got a 7 pin connector at Autozone. It was that expensive and it fit perfectly in my Hidden Hitch mounting bracket. It actually has a 4 pin right next to the 7 pin so its sort of 2 in 1. Also, the brake controller is a seperate box you buy correct? I have an 02. I just taped off that blue wire for now.
