[CA] MFD-VHF DCS-GPS-SHS-AIS Diagram

Thanks for the quick reply Chuck.

The challenge is without the red SeaTalk wire connected I'm not getting GPS or AIS lock. In my mind that implies there isn't enough voltage coming out of the SHS SeaTalk feeding the GPS however if I recall correctly when I stick a meter on the SHS I'm getting 12+ volts at the port. I'll double check the SHS but for the time being will it hurt anything to run it with the red MFD SeaTalk wire connected?
