So step two was to pry the actual toggle switches off. It was quite easy, but I didn't find what I was hoping to find. The M6 has all four window switches with the long stem toggle switch (on the top in the pic), and the M3 has 3 short stem toggle switches to make use of the actual switches in the circuit board. And the M3 has 1 long stem toggle switch to take advantage of the auto down feature.
The long stem toggle switch for the M3 is identical to the ones for the M6.
The long stem switch has the translucent "light window" integrated in all switches. It's baked in during the manufacturing process -- it ain't coming out.
So time for mission impossible: create 1/4" guide holes on both switches, dremel off the stems, prep the surface and feed a 1/2" #6
machine screw through to mount the short stem to the switch with the translucent "light window"? Crazy right? I know...
But for you nay sayers, I've already done one switch and it works perfect. but it ain't for the faint of heart. This takes time, patience, and the proper balance between gentle and forceful as to not break anything. The M6 switch also requires some grinding on the corners to allow for the same kind of travel that the M3 switches have.
Stay tuned...more to come... for now, I'm gonna go play with my daughter.
