Trailer Wiring Recommendation for a 2008 Chevy Express Van

Question

Question:

I have a 2008 Chevy Express van, 15 passenger. I just installed a tow bar and Im trying to figure out the wiring. I watched your video but Im not sure about the parts. Do I need the set up with the power converter, part #31345 from the video, or do I need part #118392?

Helpful Expert Reply:

Both the trailer wiring harnesses you referenced have been confirmed as fits for your 2008 Chevy Express Van. Either would work well but they have their pros and cons.

The # 118392 will install much easier but will not have the circuit protection. In the event of a trailer wiring short you may end up popping fuses in your vehicle or damaging the circuits.

The # 31345 will be a bit more difficult to install, but it will offer some peace of mind as trailer wiring shorts won't damage the vehicle wiring.

If your 2019 Chevy Express Van 3500 has the tow package there will be a round connector taped behind the rear bumper that a 7-way like the part #A10-7072VP could attach to. Otherwise you'd need to install a 4-way first like the part #118392.

Only a 7-way trailer connector will have a 12-volt power wire ran to the connector. A 4-way trailer connector will not have a constant 12-volt power wire. As long as the 12-volt power wire running to the 7-way trailer connector is rated for the…
