Question:

Interested in Curt Brake Controller #C84VV Want to hook up with port under dash. Is this unit setup for non splicing or do I go with the popular P2 port 90885 and a harness port #3016?

The 2009 Chevy Suburban does not have a port to plug in a brake controller which is the same as the trucks of the same year. But it does have the tow package wire bundle up under the dash, to the left of the steering column, held together with a white tag.

Pull the wire bundle out to wire in a brake controller. With Curt brake controller # C84VV you will also need pigtail # C51515. Then you can make the following connections:

Vehicle red/black wire to controller black wire for 12 volt power
Vehicle white wire to controller white wire for ground
Vehicle light blue/white wire to controller red wire for input from the brake switch
Vehicle dark blue wire to controller blue wire for output to the trailer brakes
Vehicle orange wire is not used

There may also be some connections that will need to be made under the hood to make everything fully functional. I have included a link to a help article that will help with all of this. I have also linked a video on a newer Suburban that requires the same installation.
