The correct brake controller install harness for a Tekonsha controller in a 2006 Chevy Silverado is the part # 3015-P. If you want to easily install the controller this would be all that you'd need. It simply plugs into the controller and then to the port under your dash.

I attached a picture that shows how the connector wires so if you are trying to wire up something to the vehicle and need to know which pins do what on your truck it would be the guide you would need to follow.

Would that be the same wire diagram for a 2001 Chevy Silverado? H? D.

@Carl Your truck would use the # 3025-P instead so the pin out would be different. Only difference is that the red wire would be located in opposite corner.
