This what I mean by butchered wiring. I was trying to get the bell to work in my 28 ASR. I found both wires from the stuntbox switch at position 30 cut along with many others and the ends tucked inside the large black tubing.

I finally located the bell wires with an ohmmeter, stripped and tinned them and spliced enough wire to reach the terminal strip. I also did the same with the wires from the switch at position 29.

I found these cut wires fairly fast because I encountered the exact same problem on the base connector when trying to get the break switch to work.

Question: the bell (at my best count) is at position 30. the adjacent switch is at 29 with another function pawl visible at 28, which makes me guess it could require two key strokes to operate 29.

Can anyone give me a clue as to what the switch at 29 is for and what code might operate it.
