Default 84 EZGO Curtis 1204 Controller from Melex

Okay, along the lines of several other threads but I can't seem to find the answers or diagrams I need. I have a 1984 EZGO 36v cart. I'm converting it to solid state using a complete setup that appears to have come out of a Melex Cart. It's a 1204 controller and I purchased it used and all the components came wired as they were removed from the previous owner/cart for the most part (and that's where the questions come in).

The major part of the wiring matches the diagram for a Melex with Curtis 1204 controller (FNR switch to solenoid, Controller, and Potentiometer). The Melex diagram doesn't show any micro switches or the detail for connecting the wires from them to the various components and it lacks any details on the potentiometer connections.

So, I've pulled up the EZGO diagrams with the Curtis controller and the 1204 diagram direct from Curtis as well (I'm attaching all three diagrams I'm referencing. The Curtis pdf attached, I'm referencing figure 5, pg 6). The EZGO diagram shows a double micro switch on the driver side of the FNR controls, and what I have only has a single micro switch on that side, same as passenger side. Each of the micro switches has two wires coming off them that I need to connect to something.

Also, the potentiometer has two wires coming off that are blue and black and I am assuming they go into the black/middle spade connector on the 1204 and the bottom/white connecter.

The microswitch on the potentiometer has 1 wire on one side and two wires coming off the other. The EZGO diagram seems to differ from the Curtis diagram on where those wires go. I think the single wire side is supposed to connect to the key switch and the two wire side connects to the passenger side microswitch and the top/blue spade connector on the 1204.

Right now I have one wire not connected on the passenger side microswitch that I think goes to the key switch, correct? Both wires on the driver side microswitch need to be connected somewhere but where? Lastly, there are two 18 gauge wires attached to the Battery positive lug on the solenoid. Any clue where those go?

Feel free to add your two cents here, tell me if I'm wrong with my assumptions above, and let me know if you have any idea where the dangling wires need to go.

Maybe I just need to pick up a double microswitch for the driver side of the FNR and stricly follow the EZGO diagram from there?

Thanks in advance!
