Debates and Racefla,
I'm a wee bit confused on the discussion here. I have the trailer package and it came with the 7-plug male fitting already mounted to the vehicle. It also had another rectangle plug with a wire harness in the compartment at the back of the Acadia. I believe that is for putting in a separate trailer harness.
I did have to purchase a 7-plug female fitting with a 4-plug adaptor to plug my 4-plug fitting from the trailer.
I assume that is what you guys were talking about--that the Avalanche had the 7-plug female fitting in the Avalanche that plugged into the the 7-plug male fitting at the back of the Avalanche. So both plugs were included?
