2015 Ford E450 Motorhome Brake Controller Install Harness Location


We want to install a brake box but cannot find where to connect harness to


Expert Reply:

The brake controller plug will be located behind the dash in one of two places, as you can see in the photos I've provided.

Most likely, the connector will be located behind a panel on the right side of the dash, as shown in the first set of photos. You'll need the # 3040-P brake control wiring harness to install a Tekonsha brake controller like our very popular P2.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.
