No power to shifter assembly

So we all know I’ve got a prerunner Tacoma. No windshield roll cage kinda deal. Anyways rainstorm hit the truck and now I can’t get power to use the manual shifting capability on our ac60 auto transmissions since it’s all electronically powered. I just replaced the shifter assembly with another with no resolve. Could anyone help provide info as to what I should do next? All wire harnesses seem fine i haven’t noticed any immediate burn marks on the wiring or motherboards. My radio also went out after that storm haven’t replaced that yet. But my dash lights do work. Also to mention I cannot get anything to read through my obd2 port. If anyone could just help me figure out which wires to test with my volt meter to verify what works and doesn’t would be great. I’ve checked most fuses I believe which all seem fine but who knows.

 

Does anyone know where this connector plugs into? Doesn’t seem like it has any male end

 

Isn't that the plug for the inverter? I seem to recall tapping that plug for the 400W anytime harness.
