I was just gonna post up, and you beat me to it (the blue one is my truck

back in the day.)
Though my winch control is placed elsewhere (this is the vent in the bottom left of the dash), the same idea would apply if in the ashtray. I had the local plastics place cut me a chunk of ABS, I think 1/4" thick. It's black and textured on one side, even kinda matches the factory dash. Drill holes to your heart's content and Dremel the edges as required -- ABS is soft and easy to work. It's also cheap, cost me a coupla bucks cut to spec.
I use the covered switch as a master enable, so the 12V goes in there, then out of that to the other switch, which is a double-throw momentary (i.e. spring loaded, return to center.) The 12V out of the covered switch goes into the center of the SPDT, and then the top and bottom are the in and out hots to the winch. Again, this is predicated on yours using a three-wire setup; if it's other, you might need to do a DPDT, six wire switch, which is more complicated.
The covered switch means you can't (easily) accidentally engage the winch and break something, plus it has an LED in it and looks cool
