The 2000 GMC Sierra uses a different wiring adapter than the 2006 model. When plugged in using the old adapter, the pins will not match up with the correct circuits. We offer the correct wiring adapter for your 2006 Sierra, part number 3015-P. If you're using a Tekonsha controller, the wiring adapter harness would plug directly into the rear of the harness. If your controller simply has wires exiting the rear of it, cut the black connector off the harness and wire it to the controller color for color.

Once you get the correct adapter, your brake controller should work correctly.
