OK,
I know there is some questions on wiring up the controller on here and this is what I found out.

I took the wires under the hood and connected them with the proper size MM nuts, sorry have no idea what size they are. I found them in my scrap nuts cabnet. Ok wires under the dash are as follows and this is all in the manual to. The page is 4-63 in the owner manual this should be for any GM Tahoe, Truck, Suburban any thing GM makes. You need to check the wiring on the controller to see if they matches the ones on mine. This is generic for just about all controller's.

Dark Blue to Dark Blue on controller
Red/Black to Black on controller
Light Blue/White to Red on controller
White to White on controller

Had the RV place check the wiring and it was good on the Tahoe. After hooking the trailer up I had no brakes. Had lights just no brakes. So I went back home and started looking. Fuse block on the trailer is in very sad shape. Need to do some work on it and get it back in shape after this weekend trip.
I need a good five fuse wiring block to put on it.
The Tahoe handle it well, just as the 07 did.

under the hood there is a "dummy fuse" that is normally red and marked B+, pull this fuse and replace with a real fuse.

Don't have no dummy fuse as all the lights worked. The problem was in the trailer fuse block. it has gotten so rusty it wasn't making good contact. I got it working but plan to swap it out after this weekend.

OK,
here is the fuse block on the trailer, it's so rusted it want be fixable so I'll need a new one. The bottom connection is almost gone so it has to be replaced.
