I have a 2019 Entega Qwest on a 2018 Mercedes Chassis and I would like to install a trailer brake controller. The unit has a receiver hitch with both trailer plugs at the rear of the coach. I have purchased a Prodigy P2 brake controller and was in the process of installing it in the cab and to my suprise once I removed the drivers seat to get at the green wire connector plug that Mercedes has for installing a brake controller it is not there. Has Jayco/Entegra relocated these wires and changed the connector?
