What is this part?

Anyone know what the sensor that twists into a Munci 3-speed just in front of the side plate. It has 1 wire going to it.

That sensor is the ground switch.

A switch with only one wire has got to be a ground switch otherwise it would be a dead end. The reverse light switch has two wires and the switch makes the connection between the two wires, or breaks it if the switch is open.

It's probably a ground for one of the TCS relays,

Re: What is this part?

How about the canister next to the battery? Has a spout for a hose connection and it says Rochester on top?
