    Ok first off. Excuse my ignorance, I'm new to trucks and towing etc.

    I was over in the 2nd gen section and someone said that the harness for the Trailer brake module is located in the glove compartment. I looked inside my 2016 box and didn't see anything. Before anyone asks... Yes I have the V6 Tow package from factory. Does the 3rd gen have the wiring harness pre-installed and if so, where is it?

    This is what you will need to hook up your brake controller. The harness connection is located behind the drivers side kick panel. Two of the more popular brake controllers are the Primus IQ and the Prodigy P2, I believe they are both made by Tekonsha. The above listed wiring harness will work with either one. The below pic shows the connection behind the kick panel. You can thank Jeff for the photo.

    Is that the little cubby thing behind the Drivers seat?

    Kick panel is down by your left foot, under the dash.

    It's that white plug? I thought that was the OBDII. Well that's convenient

    Mike G, thanks for the photo. It helped me to know where to poke around. My connector was tucked behind all of the other wire bundles. I finally felt part of the connector and went digging.

    I just got the 3017-p and was looking at which ports the wires are connected to and compared to what the plugin on the truck looks like. It looks like the truck plugin and the harness plugin have wires in different ports, is that correct? Are these the ground wires that should just be going to a plastic port?
