no one knows how these work?

 

You will have to find out what make/model & year it is ...

The Rubicon has no foot shifter or emergency foot shifter , On a Rubicon if the ECM detects a problem it will automatically go into fail-safe mode which is 2nd gear so you can drive slowly home/to the truck etc ...
A 2002-04 TRX450FE Foreman will use the gear position indicator to flash a problem code .. 1998-01 TRX450ES didn't use trouble codes .. The TRX450 & TRX350 had a back-up emergency shifter ..
The 2003-06 TRX350FE also flashed a trouble code for ESP problems .. 2000-02 TRX350FE didn't use trouble codes , you had to follow the trouble shooting flowchart to find the problem..
