3 electical questions with pics

[paulmcconnon]

1995 ez go series cart. Don't know which one but it has a dump bed on back.
Wiring is a bit out of order but I am trying to get it straightened out.
Pic 1 is of the solenoid. Question is where does the orange wire go?
Pic 2 is the f/r switch white wire. Where does it go?
Pic 3 is the curtis PB6 Pot box. Have black and white wires hooked to controller post 2 and 3. What do these 3 prongs on the bottom go to?
Finally the charger plug has 3 wires Black which I presume goes to Pos terminal , white to neg and a third little tiny one. Where does the tiny one go?
Thanks for any advice

That is a Marathon cart here is the diagram, hope it helps. White looks like the + power source for the MSs, near cable mark#4 on the diagram.
PS
White is + in DC
Black is -
The 3 spade terminals on the pot are the MS, it is shown in the diagram just left of the cable mark #7.
