The Universal 7-WAY Installation Kit for Trailer Brake Controller # ETBC7 will fit your 2005 Chevrolet Colorado. I have a complete step by step install video of the 2005 Chevrolet Colorado attached to show you the process.

A 4-Pole Wiring Harness to control the basic hookup of the three lighting functions running, turn, and brake lights on your trailer # 118301 is recommended. The plug-In location is under the vehicle on the driver's side.

Since you don't already have a 4-Pole Wiring Harness, you need to add this first and then use the # ETBC7 to convert it.

We also have a ball mount kit # 989900 that includes ball mounts, hitch balls, and pin and clip for a Class III. If you need a different weight capacity or need a better custom recommendation, contact me back.

If you need a brake controller # 90195 is recommended.

If your 2005 Chevrolet Colorado does not first have a 4-way # 118301, you will need to install that first, then install the 7-way # ETBC7. After the install of # ETBC7 you will have a 7-way connection toward the back of your vehicle to plug into your trailer.
