The Pot in my Annie tender has 5 lugs with wires connected.  I am familiar with three lug pots.  What are the other two side lugs for?  I cannot find any wiring diagrams for 5 lug pots.
 I ripped out the circuit board as I am installing a Zimo decoder with sound.  While the Zimo can control the volume thru programming variables and inputs, it is cumbersome with my NCE controller.  It would be a lot easier to just hook the pot to the speaker.  I just want to know if I need to use the side lugs for anything?
Thanks

power on off I believe, i.e. an on/off switch.

Thank you.  After looking at it closely I figured that is what itís for.  But Iíll be darned if I can find a schematic, that I can understand, which shows how to wire those two lugs.   Iím gonna guess that I would wire it in series between the + wire from the decoder and lug 1 (input)on the Pot?  Or would I put on the ground side?

I think you can put those 2 connections anywhere that can interrupt the power from the battery.

Well, the sound wouldn't work as wired so I bypassed the pot and wired straight to the speaker.  Works fine now.  I know I don't need the on off/volume knob with DCC but it was there and would have been convenient. 
I'm not sure how it was supposed to be wired up but my way was obviously wrong.
