Where is the Tow Wiring Connection on a 2014 GMC Savanna Van

Updated 07/03/2017 | Published 06/30/2017

Question:

We were researching hitch options for our van and came across this install video. What is the wire bundle located on the rear driver side attached to chassis? Can this be used to attach a trailer wire? Thank You!

The 2014 GMC Savanna Van has two possible options for trailer wiring. If the van is pre-wired for a towing package or it is not pre-wired.

The wiring plug that you mentioned does not look like the correct wiring plug needed if the vehicle is pre-wired for towing. The plug end for the pre-wired will be a OEM car connection that is a somewhat large round plug. See photo.

If your vehicle is not pre-wired, then a harness kit like Tekonsha T-One Vehicle Wiring Harness, # 118392, will work well on your Savanna van. This harness will plug into existing wiring plugs at the taillights of your van and will supply a 4-pole connector to run trailer lights.

If you have the large round plug then you will need the Hopkins Plug-In Wiring Harness, # 41155.

I have attached two installation videos for both of these wiring harness for you to review.
