Hello board;<br /><br />Just fishing for info on this. I have a lowrance x125 I would like to install on the bow of my '93 pro v. Do most of you run your power supply wires all the way from the back (cranking battery), or can I get by tying into one of my trolling motor batteries (24v system). (I realise I'd have to wire the graph so that 12v was achieved)<br /><br />Thanks for any insight.
