Question:

I have a 2004 Motorhome which sits on a Ford E-Series Chassis. Im wanting to run Trailer braking system to the back. I'm trying to add a 7 wire plug. Currently I have no trailer lighting at the back of my motorhome. There is no way to tie into the tail lights. Under the motorhome I have found the wiring going up into the motorhome. There is male and female plug that it connects to. Im hoping that you have a T that I can plug into and then run the wires to the back. Wondering if you have a easy way to tie into those without cutting and stripping the wires.

We do have options that will work for you, but there is no T-connector wiring harness that will simply plug in to your motorhome.

Since you have no trailer connector at all on your motorhome, you will need to do some hardwiring. First you will also need to install a 4-way on the rear of your motor home like # 18252. Next you will need the 7 and 4 Way Installation Kit, part # ETBC7. The # ETBC7 kit comes with 25 feet of duplex wire. I am including a link to a help article page on how to wire the # ETBC7 kit to your motor home.

I am including a link to a FAQ page that will describe how to wire the 4-way wiring kits to your motor home.
