I would like to install a 4-way wiring harness on my 2018 GMC ACadia. i don't have the factory tow package or connector or anything so what wiring harness do I need?

Expert Reply:
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.
