Hi George,
Since you're wanting to add trailer wiring to your 2014 GM Savanna van, you'll want to use the Curt T-Connector Vehicle Wiring Harness w/4-way Flat part # 55540. This wiring harness will plug directly into your van's existing wiring with no cutting or splicing needed to quickly and easily give your van a 4-way flat to run trailer lights. I've linked an installation video from when our techs installed it on the same year, make, model of your van so that you can follow along as you install it.
What kind of trailer are you planning on towing with your Savanna van?
