Hard wiring to upfitter aux switch question

[gpatz]

I want to hard wire a Furrion WiFi Monitor to AUX switch 1. What has me confused is that the fat blade wires only have 1 wire and the power cable for the monitor has 2. Which wire do you connect to the upfitter wire or do you connect both?

one is positive and the other is ground on your unit.

Just curious, how did you run the wire to the display?
