I am wiring a PS 30 and PS 31. I have a transducer stick from fishing specialties which has a hollow center and I was going to run both the power wire and transducer from the PS 30 wire up the center of the shaft. Is this going to cause interference? The only other option is to run the power on the outside of the stick on one side since the wiring from the PS 31 will also be on the outside. I would have to try and run both power wires on one side of the stick and the transducer on the other. Thanks for the help
