Quest 2 voltages for six contacts on back

I am setting up a Quest 2 on a motorcycle. Room is tight,.. there will be some custom wiring involved.

Some of you can probably save me a lot of time if you can explain to me what the six contacts on the back of the unit are for. I realize two are probably audio, so they won't be a factor. I would like to know, though, what each contact is for.

The important part, though, is which contact is +5VDC and which is ground?

Here's a pic showing the contacts. The software won't let me post a link to a pic because I am a newbie here. Take three spaces out of the following to see the pic.

Thanks for any help,

C'mon folks!! Surely someone out there knows these kinds of details. I tried Garmin support and they didn't know what I was talking about -- they said the only way they could help was to sell me cables and mounts, etc.
