Since I am using the Winters/Art Carr shifter, I needed to fab some kind of reverse switch. So I went to Radio Shack and picked up a micro roller switch and built a mount to attach to the shifter:
My idea was to use the existing holes in the shifter plates to engage the switch as it comes around. So I turned some aluminum bar stock down as a ‘wheel”
I cut two just in case I wanted to activate a switch in the future (park/neutral) The wheel will sit between the gold plates:
I cut some aluminum angle scrap and mounted the switch. I can adjust it up/down and back/forward for proper engagement:
Wired it up to a relay as a switched ground and it works great. Here a couple of close ups:
