Water pump Fuse location help

Hi Fellow Thor owners! I just registered but have been reading alot of info on my new to me 3004 thro e450 toy hauler. I love it and have had a goodntime with it already.
The problem I am having is finding the fuse location for the water pump.
I checked starting at the pump that there is no 12v coming in and tested with different grounds incase my ground was faulty. Traces back until the wire goes into fridge wall and no power. I tried from the switch above the stove the light comes on and there is 12v going into the switch and coming to the pump. Some where between the pump and the switch there must be either broken wire or a fuse but I can't seem to find one yet. None of the fuses at the control panel are blown and all breakers are good as well. I can't seem to find a wiring diagram to trace the routing of the white green wire pair that goes from the switch to the pump. Dies anyone have any advice on where to look next?

Probably not a fuse between the switch and pump - likely a bad connection, maybe rodent issue.

There have been some mice in the coach.
I'll try and get wiring diagrams from the thor website, but it seems that the owners manual is what can be found.

They may not have any further diagrams for your coach, but even if they did - they are almost worthless. Get a wire tracing kit is your best bet,

Not sure what a wire tracing kit is. I'll look it up. Thank you

OK so I worked from both ends and have gotten to the short or cut wire being under the plywood in a chase from the passenger side to the driver's side there is power going into the floor but no power coming out from the other end of the chase. I'm not sure if the chase has to be cut open or if it is accessible from below the rv. I'm thinking of running a new wire if I can't access the repair

Any thought or tips?

Run the new wire; zip tie it in place.

Use marine grade shrink tube over the splices.

OK I was able to access the wire in a weather protected rain gutter thing under the rv. It was definitely chewed wire. I blew all the mice poop n bedding out the closed everything back up.
Thx for the help guys
