The 2014 Chevy Suburban does not have a place to plug in a brake controller but it does have a tow package wire bundle that you will use to wire up a brake controller.

The wire bundle is located up under the dash to the left of the steering column. It should be held together with a white tag which also lists the wire functions.

I have included a link to our help article that explains the installation. There may also be some connections that need to be made under the hood to make everything fully functional.

In the tow package wire bundle you should have a red/black wire, white, light blue/white, dark blue, and orange wires.

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

I have also linked a video that you can use as a guide. If you need a harness with bare wires at the end that plugs into a Tekonsha brake controller use # 7894.
