2007-2013 GM Full Size SUV Suspension Warning Light Fix Module (GC2M)

At first it was difficult to locate a pink wire that was switched 12 volt. I continued to look I places that I suspected should be switched voltage. Then I got clever, I ordered a switch with a light on the button, I wired it so that when on I have a blue (visible) light on the lower dash as a reminder to turn it off when not in use. And if I forget to turn it on the dash board warning will remind me that the suspension needs service. A relatively elegant solution to ripping apart the wire bundles in the dash.

Plugged it in and it worked great
