Cab Light Button beside airbag control

[Bannyto5]

I have the button I bought off eBay. 15061687. 06 GMC Sierra 3500 diesel. I ordered harness 12171974. It should hook up to back of button and to male hookup that was taped to main wiring harness. It is located right beside passenger air bag switch. The wire is just right there. Will this male plug hook up to the harness I ordered? Been looking a long time for harness. Thanks

This Button was originally in Trucks that have a Plow package. Its purpose is to run a Emergency yellow rotating "Beacon" light on the roof when plowing snow.

The "Tow haul " button is on the end of the gear selector.
