This is a Tekonsha P3, seems like a few guys on here have them.
I didn't want a knee knocker, really wanted it in the center cubby thing, with the folding door.
It has to be hard mounted though.
I also wanted it suspended from the top, so there would be room for my phone for Pandora.
Lets cut to the chase, I welded this to the Tekonsha bracket, I'm sure you could do something similiar with bolts if you don't weld.
That allowed me to make use of the top mounting bolt for the cubby hole.
There's a PDF on removing trim available here:
WK2 Jeeps - Interior Trim Removal
I dunno what this is a picture of... Maybe showing that the lid of the cubby comes off.
I drilled a few holes in a slot in the top near the LED, right in front of the mounting tab, so my brake controller mounting tab could slide through that.
Which puts the mounting assembly here.
It wouldn't sit pretty with the iphone adapter plug's fat trim ring, but removing that made a good spot to bring the brake controller cable in, so that trim piece had to go.
Bonus was, it made the cable for the phone a little longer, I taped up the pigtail up in there cause with it's new found movement I didn't want to rub and coating off the wires.
Here's another picture I took, not sure why. This cupholder panel has to come out before the cubby comes out. Radio faceplate thing too.
Do this with these:
Then it's the gray plug, up above the OBDII port.
Done. Door doesn't hit, controller mounted, plenty of cable for the phone.
Hope that helps somebody.
