I sure can help you out with installing the P2 brake controller # 90885 in your 2007 Chevy Avalanche.

The brake controller white wire will go to the truck white wire for ground
Controller black wire goes to truck red/black wire for power in
Dark blue on the truck goes to controller blue for output to electric trailer brakes
And light blue/white on the truck goes to the red wire on the controller for input from the brake switch

With that and those connections made under the hood you mentioned (if applicable) you will be good to go! I have also linked a help article that covers all of this for reference.
