Where do all the wires run

[Stephene1219]

I have a 2022 2922 and while TM does include wiring diagrams there is no information I can fin on where the wires actually run. The reason I ask is because the Battery monitor that cam with the TM is really pretty basic. I would like to change it out for one that give a lot more info like the Renogy 500A battery monitor. This requires a Shunt so I would need to run wires from the battery compartment to the current monitor location which is by the sink.
