Question:

I have the van, a tow button for gearing - nothing else? Do I have plug and play? What do I need buying a travel trailer Wednesday

First, in order to determine what hiring harness you will need, you will need to know what type of connector the trailer has and if it has electric brakes. Most trailer use either a 4-Way flat, or a 7-Way blade style RV connector. I recommend installing what is called a multi-tow system that includes both.

You will first need to install a 4-Way wiring harness, 118392. This is a simple T-one connector that plugs in line with the vehicle tail lights. I have included a link to the installation details and a video showing a typical installation for you to view.

Next you will need a 4 and 7 Way Installation Kit, # ETBC7. This will provide a 7-Way and retain the 4-Way connector at the back. It also includes all the wiring and circuit breakers to make it fully functional. If the trailer does have electric brakes, this harness also provides all the wiring needed to install a brake controller. I have included links to 2 FAQ articles and a video that explain the installation of an ETBC7 kit. The kit does come with 25 feet of wire, but with such a large van, you may need another 5 or 10 feet of # 10-2-1.

For a brake controller, I recommend the Tekonsha P2, # 90885, because it is easy to set up and easy to use. I have included a link to the installation details for the P2 for you as well.
