Melex 252 forward/reverse switch wiring problem

[cdj901]

i have replaced the f/r switch on a old model 252 . all battery cables are in the right place but there are 3 smaller wires that im confused as to the location, 2 of which are the micro switch, i believe them to be wired correctly but the bottom terminal of the f/r switch also had a small wire that was missing all but the connector. so my question is what wire other than the battery cable connects to the terminal at the 6 oclock position of the forward reverse switch . i have tried to find wiring diagrams but all they show are the battery connections. any help would be great. thanks!
