I have a 23zxr 20 and have a mega 360coming. I am going to go ahead and run new 8 gauge wires to the front for power for it, and some kind of live sonar and add another graph for the front. For those who have done it, is it easier to go down the port side with the wire, or the starboard side, also I know that there are extra sets of power already wired to the front. They are hot all the time, and I can turn on my graphs and trolling motor even though the switch in the back is turned off, is this normal? Thanks for any responses, I just want to make sure everything is done right
