Installing a 7-Way Trailer Connector on a 2008 Chevy Express Van 3500


I have a 2008 Chevy Express 3500 15 passenger van with the trailering, but no hitch. I have installed a hitch, and am told the vehicle should already be wired for lights/brakes, but I cant find any of the wiring where its supposed to be. 1. Any way to find out if the wires were ever installed? 2. Where would they be if theyre there? 3. If theyre not there, how do I hook up trailer lights? The brake isnt a necessity right now, but I have to have lights ASAP Thanks

If your 2008 Chevy Express Van were already set up for trailer lights and a brake controller, it would have a factory installed 7-Way trailer connector at the rear of the vehicle or a wiring harness located inside the driver side frame rail near the rear of the vehicle. Look for a round plug with a cap. If you find this plug, you will need part # 30955. Scroll down on the product page to see what the plug on the vehicle will look like.

If you cannot find this plug on your vehicle, it may not be wired for a trailer wiring harness. In this case, you would need to install Tow Ready Custom Fit Vehicle Wiring, # 118392. I have included a link to the installation details and a video showing a typical installation for you to view.

With the 4-Way installed, you would then need to install a 4 and 7 Way Installation Kit, # ETBC7. I have included links to an FAQ and video that will explain the ETBC7 installation. It will also explain how to install a brake controller.

If you find that you have the plug for a 7-Way, the blue wire for electric brakes will be already ran from the back of the vehicle to cab of the van, under the dash near the emergency brake pedal. For a brake controller, I recommend the Tekonsha P2, # 90885, because it is easy to set up and easy to use.
