Dash harness meltdown help

I found the wiper switch that matches up...think I can make it work? Think it will fit in the dash?
Besides that, How can I get that gauge inset round plug to match up with my cars? The wires dont even look the right color...!

That wiper switch (from the '65?) does not have the long shank that your (and my) '64 switch does. Neither does it have the little black button in the knob for the windshield washer pump.
I think the long shank was to clear the pushbuttons, so the short shank switch may well not fit your '64 dash.
Cool move, though, I love my pushbuttons! My parents' '62 Fury had em. (the car I learned to drive in)
