Ok 2 questions

1-did everyone get a 5 wire plug harness in the cargo pack?

2- What the heck is it for? ???

I give up, what is it for???

Maybe to plug into a connector on a trailer or something for lighting.. Shot in the dark.

Maybe a trailer plug if you remove the factory 7 plug.

Yep that may be it. the round 7 pin plug has a socket that looks like this would plug into.

I bet it's for making your flat pigtail hookup.

That is exactly what it is for, I have both the flat style and the round style adapters for my Chevy Truck.

It is for the trailer brake module. It plugs into the fuse box and the wires attach to the Aftermarket trailer brake module.

I think you are correct.
Today looking for the parking brake release I saw a socket at the bottom edge of dash next to the hood release.

I had to get the manual out to find how to take the park brake off

The plug near the E-Brake is probably the OBD (On Board Diagnostics) connector not for the brake controller. Does the plug fit in the socket in the back by the hitch?

I'm glad I'm not the only one that had a small problem with the parking brake!!

I was taking one for a quick test drive, and it was dark out. The previous driver (right before me) must have had trouble with the inside lights - they would not come on when I opened the door. took me a couple minutes to find out how to turn the dome light back one. Then I accidentally opened the hood, so I had to get out and close it. ??? Took me another minute to finally realize how to disengage the parking brake.

Thanks guys--I was wondering too!
