I want to hook up a Garmin 740 to a Icom 412 so that the DSC function will work. Does anyone know what color wires go from the garmin to the icom?

Here you go .....
The 740 uses it's power ground as a NMEA ground so your 740 is already grounded. The Icom 412 has two ground shield wires that will have to be connected to a common ground source. Here's your connectiion colors.

Where can I get one of those "wire terminal" or "wire connectors" from?
