Snap in and done
I used a Curt 7-pin T-connector to wire in an LED light bar under the tailgate of my truck. It couldn't have been easier. I pulled the release tab off on the back of my existing 7-pin connector, attached this T inline, and plugged the light bar into the new 4-pin. Everything is hidden behind the bumper and I still have a 4-pin and 7-pin available for towing. My light bar had a separate reverse wire so I actually spliced into the center wire of the 7-pin on the T.
decent price for hidden hitch with higher capacity
For model 76004, square tube with higher capacity. You can install it yourself, kinda, but you really need help to put it into position. The Colorado step bumper and bumper support are light weight and can be handled alone but the new hitch cannot. Plus it has a very tight fit around the frame rails and must be pushed on with some force or even with a mallet. The fit on mine was just right. The square tube is hidden behind the step bumper. Use 1/2" drive socket & wrench as torque is 100 ft lbs.
