I found an eBay listing that shows the 1032 instructions.
Apparently your trolley works best using the B-U terminals. 10-4.
I guess I misunderstood about using the ZW. I thought you wanted to used the ZW Accessory output to power "all" your accessories (including this new "accessory" that performs automatic trolley control.
But if you want to "isolate" your trolley system and use JUST the 1032 to power all-things-trolley, then simply power the automatic trolley system using B-C terminals and the trolley track voltage with B-U (adjusted to a suitable speed). In this context, it doesn't matter if it's B-C or C-B in terms of orientation of the wiring. Likewise, it doesn't matter if it's B-U or U-B in terms of orientation of the wiring.
