Looks like the same unit I installed on our 1.5 Equinox Premium. I bought it as an OEM accessory through the dealer. I don't have to know but, I bet the labor charge was significant (And should be). On the Equinox, the whole rear bumper cover, up to the tail lights, including the tail lights, had to be removed. The original backup bumper is replaced with the hitch. (A significant aluminum structure that should have been returned to you unless you got credit on the install). On the Equinox removing the original backup bumper eliminated the screw-in tow hook feature, but the safety hook holes on the receiver could be used instead.
The only change I made on mine was the plug. I used a twist-to-latch 7-pin plug, as used on the 2.0 vehicles, (using only four positions), because I thought it would look neater than the adapter for the flat four connector. I may never use it but, I have a small aluminum trailer that could be used with it as long as I load it lightly.
