I need to wire up my bow graph, I have an open circuit on the junction under my console, but is it better to wire it straight to the battery? Or does it not matter? I tried going through the wiring path all the way to the battery, but get getting caught up on something and couldn’t get my wire puller all the way through. 

Personally - only the TM wires through a dedicated breaker to the battery....everything else goes through the junction/circuit breaker box.

They have the trolling motor wires run through the same conduit but I thought the trolling motor wires were supposed to be kept away from the graph/transducer wiring?
