The correct brake controller install harness for installing the Prodigy P2 part # 90195 in your 2001 GMC Sierra 2500 is the part # 3025-P. This plugs right into the junction box under the dash of your truck.

In the attached install video you'll see how this is done on a very similar 2002 Chevy Silverado.

If there's a connector already in the port you can simply unplug it and plug the # 3025-P in it's place.

Sounds like you may have a harness already plugged in to the port on your junction box that has blunt cut wires already present. Since I am not sure what color wires you'd have the best solution I have would be for you to use the picture I attached as a guide.If you match the colors of your brake controller wiring to the pin locations in the picture by color you'll be set.
