I just bought an LT with the towing package. Love the car but the wire towing bundle in the glove box is confusing to me. It has open wires on one end and the rectangular connector on the other. I went under the rear end of the car and looked at the connector by the hitch and it has a round receptor that does not fit rectangular connector on the wire bundle. What am I missing or not understanding about this set up? Was there something the dealer was supposed to have done to get this ready? Is this the wrong wiring bundle? Any help would be very appreciated.
