I don't see how driving through high water or pushing a "dead" truck in the rain will cause wires to switch places in a plug, but I suspect the wires that plug into the ignition switch plug are pinned wrong. When the ignition switch is in the start position, the acc wire/circuit will not have voltage on it.. The pink wire at the plug is the ignition wire, not the brown wire. I think that possibly the pink wire and the ACC wire are switched.. Comparing what you have to the wiring diagram will tell you what wires do what, and where they should terminate in the plugs.

I offer this advice to anyone trying to solve an electrical problem.. Go to the ELECTRICAL forum on this site and down load the wiring diagrams for the vehicle year being worked on. BTW, this is a good time to correct that "jury rig" in your wiring.
