You will need a brake controller and a brake controller installation kit, item # ETBC7, to install trailer brakes on your 2004 Mitsubishi Endeavor.I recommend the Tekonsha P2 Brake Controller, item # 90885, which is a very good seller and is also easy to use.

The ETBC7 installation kit includes everything needed to install either brake controller, per the brake controller manufacturers instructions. You will also need a circuit tester, item # 3808, to find the brake circuit under the dash that has power when the brake pedal is pressed.

To install the 7-Way adapter, included in the ETBC7 kit, you will plug it into your 4-Way connector, and then connect the additional wires.

The additional wires would be installed as follows:

White: Ground, attached to a suitable location on the vehicle frame.
Black: 12v power lead wire, run to the vehicle positive battery terminal, with the 40amp circuit breaker included in the # ETBC7 kit.
Blue: Electric brake wire, connected to the blue electric brake wire coming from the brake controller in the vehicle cab.
Purple: This is an auxiliary wire, and can be used as a 12v power source, or to power a reverse light or reverse lockout function if needed. If not, this wire can be tied up.

The 4 brake controller wire functions are:

White: Ground, attached to a clean piece of unpainted metal.
Black: 12v lead, attached to the vehicle positive battery terminal with either the 20amp or 30amp circuit breaker included in the # ETBC7 kit. Use the 20amp breaker if your trailer has 2 to 4 brakes, or the 30amp if the trailer has 4 to 8 brakes.
Blue: Electric brakes, attached to the blue electric brake wire from the 7-Way adapter.
Red: Stoplight switch, normally located directly off the vehicle brake pedal.
