The wiring harness I recommend for your 2018 GMC Acadia that does not have the factory tow package is the T-One Vehicle Wiring Harness # 118720 because of how easy it is to install on your Acadia; you will only need to plug it into the connection behind your bumper. I have added a cut out of the linked instruction manual which shows where that connection point is.

In addition to the easy installation of this harness I also really like it because it is manufactured by Tekonsha, who has a strong reputation for creating quality wiring products.

I have added a link to an installation video of this harness on an Acadia for you to check out.
