Any switchable power connection that can handle to necessary amps will work. I added mine to the main power rocker switch which works out nice for me.
Just remember to turn switch on before powering up graph. Don’t ask me why but it was recommended in instructions.
Be patient on the graph to “find” the ML transducer to first time using. Make sure it’s outside so it can get a reading off heading sensor.
Don’t forget battery drain wire in power connections.
Post some pics or vids of install and fishing.
