Wiring- Hewes LT20

Livewell pump not working from dash. Hot wire it and it’s fine. Ohm the switch- it seems fine.
Looking at Hewes RF21 wiring show brown/white & black for the Livewell. I have two Brown wires. I think the white is faded out. I also have 4 black.
Either Brown to any Black is HOT, with switch On or Off. Even with ALL switches to OFF>

Suggestions?

Hanckel…

Finally got my head in the bilge with VTM…Kept switching leads/wires/switches. At last- got the Live Well #2 working. Could not find voltage for Live Well #1.?.. But, one is all we have/need.
