What type if controler is it....Reese?

You need to go to whoevers controler it is, and get a wiring diagram....I have one for a Reese if thats what it is.

Do you have a 7 pin hook up at the bumper now, or is it just the basic brake, turn, tail lamp hook up? To hook up the brake controller you'll need to hook the brake wire from the box to a relay, and a large (10 guage if I remember correctly) from that to the brake pin in the rear connector.

Like Pocho stated.... you gotta figure out what type you have

You can get the basic four pin trailer hookup using a T-One adapter that plugs into your wiring behind the back bumper.

The four wires are for:
Taillights
Right Turn
Left Turn
Ground
You will probably also have to switch to a heavy duty flasher for the turn signals.

To get the other three pins (including brakes) you need:

Black wire - constant 12 volts to power the trailer or trailer battery
Blue wire - trailer brake activation
Purple wire - backup lights

This site has some useful diagrams. http://www.etrailer.com/faq-wiring.aspx

You still need to figure out what type controller you have...... it's easy to hook up, basicly it's a transmitter that transmits a signal to the other black box that's mounted on the trailer. The box on the trailer applies current to the electro-magnetic brake caliper thingies which in-turn apllies the brakes etc....
