Your 2021 Nissan Armada is already prewired for a 7-way and a brake controller. You'll just need a brake controller, a 7-way trailer connector and the relays needed to activate the tow package.

For the 7-way, use part # N40975 which provides both a 4 pole and a 7-way. The connector will plug into the US Car connector located under the rear bumper, and includes the needed relays. You'll also need the # 18136 mounting bracket for the trailer connector.

For a brake controller, I'd recommend the Redarc Tow-Pro Liberty, part # RED24FR. The Tow Pro Liberty is a remote mount controller. The control unit installed under the dash, where it's out of sight and you won't bang your knees on it. The brakes are adjusted using the control knob which can be mounted anywhere within the driver's reach. An unused switch knockout in the dash or the center console is a great spot, but it can be mounted through the dash as well. A mounting bezel like part # 331-TPSI-001 is also available for a professional looking installation. You'll also need the # RED69FR pigtail and the # 3050-S wiring harness. The pigtail and harness would wire together, color for color.
