If you have a Bully TC-301 brake controller it should have the following wiring colors and codes:

Black = ground
Red = 12 volt power
Blue = input from stop light switch
Yellow = out to trailer brakes

This is different than a connector like # 3025-S. On it the colors are black for 12 volt power, white for ground, blue for output to trailer brakes, and red for input to brake controller. But on a 1996 Chevy Suburban you will need to hardwire in the controller because there is no port or wire bundle for a plug and play type of harness.
