Some of the pins in those, such as switch illumination, always on, key-on, or ground, could be useful in controlling DIY accessories. Others go off into nowhere and can be safely chopped off and taped shut.
The two Illumination wires are usually colored Orange with a White Stripe, and Violet. They usually occupy a standard location in a plug. Both are necessary to light up the internal light in the switch. Note my use of 'usually'. YMMV! Test before committing.
Leave enough wire to connect to the new stuff when you chop off the unknowns.
