Gauge cluster wiring.need help.

[greenmachine]

Wondering if anyone here on CP might have a protege cluster wiring diagram that they might be so kind as to share? I'm from FEOA and i know yoda's on here somewhere along with a few other guys and a few people told me to come here in search of answers. I have figured out most of it by my lonesome but i'm flat out lost on one wire in particular. center (black) plug... 1st wire going from the left... GRN/red .... looking at the back of the cluster it goes down to a "j" which has a jumper behind the "paper" then goes over and ends on one of the screws that hold in the speedo. what does this wire do for the cluster? on my escort cluster the GRN/red wire is fuel cutoff light signal but i know this cluster doesn't have that. help me out.

Sounds like a ground.

lol sounds like? the path of the wire sounds right to be a ground but the color throws me off. :/
green for a ground?

Looking at the FSM, it looks to be the speed sensor (reed switch). Goes to the ECU for I don't know what, to the passive belts system, and to the cruise control box. I've used it log speed with my standalone ecu.
