Question:
I want to install a drawtite class III receiver hitch on my 2017 Acadia Limited, but it is not equipped with the factory towing package. The wiring packages I see on your site say that they plug into the factory towing harness. If I dont have that, what package do you offer?

Good question!
The T-One Vehicle Wiring Harness # 118270 will fit your 2017 GMC Acadia Limited whether it has the factory package or not. The plug should be located at the rear of your vehicle behind the rear passenger side tire (see attached photo). If you had the tow package you would simply make this connection and be done with it but since you don't you just need to use the fuses and relays that come with the T-One to activate the wiring. We actually do this exact thing on another 2017 Acadia Limited and I have attached the installation video for you to reference.
Since you are also installing the Draw-Tite Max-Frame Trailer Hitch Receiver # 75528 which has a bracket for the wiring you just need the bracket # 18144 for a clean looking installation. Attached is an installation video for the Draw-Tite trailer hitch for you to reference as well.
To round out your towing setup you also need a ball mount kit. You may be interested in the Curt Class III Ball Mount # C45036 which comes with a 2" hitch ball and has a 2" drop but you will need to check out the attached ball mount article first to make sure that the drop is correct for your towing application.
