I have a 2003 386 with a Raymarine C70 chartplotter at the helm, radar, autopilot, ST60 wind, speed and depth. I wanted to connect AIS and DSC at the electical panel where my VHF is located. The chase hole at the base of the pedestal is so full of wires that I don't think I can get another one through let alone the four for AIS and two for DSC (all 18 AWG). Can anyone think of a solution or work around?
