11-13. While wiring the switch itself is fairly simple, it’s not quite so straightforward when it comes to mounting it in the stock ’68 C10 ignition switch location. The bezels themselves need to be opened up and some way to affix the button needs to be sorted out. In the stock application, the button snaps in place on the dash, but the thickness of the C10 bezel prohibits that from being possible. I whittled out a small retainer ring that fits around the button’s housing and can be held in place using a hose clamp. Slide the button and the outer bezel into the stock ignition hole in the dash, slide the spacer, retaining ring, and hose clamp onto the switch from behind the dash, and tighten the clamp until everything’s nice and snug.
