When I disconnected the captioned original Digital Compass when replacing the dash instruments, I neglected to properly take note of where the compass wires went. I'm hoping someone has installed one and able to provide some advice on where the four wires are supposed to be attached:
The four wires coming from the compass are Black, Red, Green, and White. The Green wire appears to be capped and not used in the original installation - so my first question is: What's the green wire for?

So then, if the Black and Red wire provide the electrical power to turn on the compass, what's the White one for?

The boat is 1989 Revenge 25.

Many Thanks,

In cables with four wires, the color combination of


is in common use, especially with paired conductors. I don't think these colors will necessarily conform to the usual color codes used on boats.

I think I got it! I looked at the online manual for a current model KVH Digital Compass. Now there are 7 wires!

The Red/Black provide the power. The White wire is the light! The Green wire may be an NMEA OUT - hence it was not in use with the original installation.

The usual wire insulation color for instrument illumination is BLUE.
