Movin' on.....two weeks into the build, I get to work again on something Bluetooth related.

I chose to put the input selector switch between the mirror adjustment **** and the cupholder. With the panel removed from the console, I mapped out where to drill the hole. Looking at it from the bottom, a small portion of the unused plastic switch holder needed to be trimmed away for the securing nut to fit through.




The drill press was the perfect tool to trim that piece of plastic away so I began to line the press table with old newspaper as padding to prevent the panels painted surface from being scratched. Got everything lined up, clamped and secured in place, ready to make that trim. That factory switch holder became a perfect guide in helping me decide where the hole center should be.




I used a 1-1/2" hole saw to remove just enough of the black plastic section making sure not to drill completely through the panel.




I replaced the hole saw with a multi-step drill bit to drill through the panel.




The switch's threaded outside diameter calls for a 1-1/16" hole but my step bit can go from 1" then skips to 1-1/8". As a precaution, I marked the bit at 1" and stop there hoping I wouldn't need to go any larger.




...and, to my luck, a 1" hole was enough to make the switch fit through that hole perfectly!


The panel and the switch were assembled together to see just how it looked and I was very satisfied at how that turned out.





Step-4, Done.
