Pacis,
Considering bilge pumps are one of the few items usually wired directly to the battery, it should be easy enough to identify through the process of elimination which wires are for the bilge pump. Ruling out the main cables, should only leave 2-3 other wires to check. A check of the wires from the bilge pump for color coding could help reduce the number of wires you need to check.
Whaler does use a color coding chart that lists
Bilge pump wire as brown or brown/red.
fwiw

Disconnect the negative leads to the deep-cycle batteries leaving the cranking battery connected. Trip the manual switch of the bilge pump. If it runs you've found the power source. If not, connect one lead to each remaining battery until you find the one that works.

pacis,
Based on your last post-are you thinking you need to leave the battery switch in a certain position for the bilge pump to work?
