Question:

Hey There! I have a 2009 jeep grand cherokee that I would like to use when towing my 2003 Viking Saga pop up trailer which has electric brakes and a 7 pin connector with six wires going to it. I have no reverse lights on the trailer. What do I need to wire up the Jeep so that I could have a brake controller and the rest of the other mandated lights?

Expert Reply:

How's your 2009 Jeep Grand Cherokee equipped now? If it doesn't have any type of trailer wiring already then the best thing to do is to add a 4-way connector and convert it to a 7-way. Reason being is that the 4-way, like part #HM11142555, is easy to install because it plugs in behind each tail light. No splicing at all. Then use our # ETBC7 kit to convert that 4-way to the 7-way. The kit plugs into the 4-way you already installed for the lighting functions and then you run the 12-volt wire the Jeep's battery and run the blue wire into the cab for the brake controller. Everything you need is included with the kit except the controller itself. The 7-way has a wire for the reverse lights but you can cap it off since your trailer won't use it anyway.

If the Jeep already has a 4-way then you just need the # ETBC7 kit and install it the same way.

Then for the controller I recommend the Hopkins Agility, part # HM47294, along with the wiring harness # HM47685.

If the Jeep doesn't already have a hitch I like the Curt # 13251 for it.
