I just spent a few hours with my new-to-me 2011 Sea Hunt trying to figure out what the prior owner did with the electronics that didn't come with the boat. All I got was the antenna and two Garmin mounts on top of the CC with lots of wires,etc. It looks like he had a Garmin 700 series GPS/FF and a Garmin VHF. I'm going to flush mount my new electronics and figured I may as well go with the same Garmin electronics in order to make things easy. I found the PL-259 antenna connector and power for the radio via black and red wires. On the GPS/FF side, I found the "pigtail" that connects on the back. The transducer is already on the boat and the wire connects to the pigtail. The problem is that I found another connector which I am guessing is a NMEA 0183 setup to connect the GPS/FF to VHF. It's a 6 pin male plug so I'm guessing that whoever installed the radio made up a 6 pin female plug on the radio end. Does that make sense? Now to make things easy, i was thinking that I should simply get a Garmin 720S with a Bluechart g2 Vision and get a Garmin VHF 200 so both are NMEA 2000 compatible and just hook them up via the NMEA Bus rather than dealing with soldering wires and making a new female NMEA 0183 connector for a VHF. Does this make sense? Here are a few pictures. Sorry but they're not the best.

6 pin male plug that I think is the NMEA 0183 connector for the VHF:

Kind of a hack job on the NMEA 0183 cable but you can see the little wires:

Your going to hate this answer, but cut everything off, get yourself a set of euro-connector blocks, and rewire everything according to the manual. Use bus bars for power and ground connections to switches.

Make a block diagram showing each color and where it connects ahead of time and follow it when making connections.

Later, when you go to take out a component, you will know how to attach your new unit.

The shrink wrapped connections in your pic are good, but prevent you from seeing what goes where and making any changes or troubleshooting connections.

The 1st pic is Garmin's NMEA 0183 connector, will plug right into most new Garmin plotters which will have a matching red connector on the back.

the 2nd connector looks to be custom, and you are probably right it's a custom quick connector for the VHF, but make sure it's not a transducer connector... follow it....
