i cant ind the instructions with my FCD and cant identify what wires do what.

There are 3 wires that are connected to the POT when i opened it up.

Theres a green, red and black.

The POT has three terminals, red on the left, with a 100ohm resistor

(BR, BL, BR).

The middle green wired terminal has 2 diodes connected to it for some reason and finally the last terminal just has one wire going to it.

Can anyone identify these and tell me which needs to be wired where?
