1991 YJ VSS diagram

Can anyone explain the schematics of the 1991 VSS? It has two wires. I need to know what each wire does. It has to be 1991. The only year when they had a 2 prong VSS. mechanical and electrical.
thanks

Thanks but that's not what I am referring to. I guess I shouldve worded it differently. I am just referring to the electrical side. The Electrical VSS has two pins or (two wires running to it). One goes to the PCM and I am not sure what the other does.
