If the trailer you are planning on towing does not have electric brakes, you can simply leave the blue wire on the 4-pole to 7-way Adapter, part # 30717 disconnected. You can bundle it up, and zip tie it up out of the way.

If the trailer does have electric brakes, a brake controller would be needed to actuate them. The blue wire would be extended and ran under the vehicle to the engine compartment, and through the firewall to connect with the blue brake output wire on the brake controller.

To see a video of the Adapter being installed, click on the provided link. Although the video shows the adapter being installed on a different vehicle, the video will still provide information that should prove helpful for your installation.
