Do I understand that if you put the roll bar down the red indicators light on the switch? If so, I think a code should be stored in the controller for the roll bar. You can retrieve the code by connecting an LED between pin #7 of the diagnostic connector and ground. Short the leads of the LED for three seconds and a code will blink out. Repeat until all codes are retrieved.

Regarding an LED, I would put a 1k-ohm resistor in series with the LED or get an LED that has a built-in resistor.
