Can anyone confirm that the black portion of the power cable (between the cradle and the voltage converter) just has two wires, positive and negative?

I was wondering this myself

Looking at the wire it only has two in so why would it have more out of the converter? Plus there is only two pins to feed to so on that basis I am going for just two wires

Are you shortening it? Due to the mass of wiring

Yes, that's it. Here's a pic from Advrider Forums:

Thanks for that. I had noticed the points you mentioned but just wanted confirmation.

What I want to do is wire up three bikes but only use one cradle. I'll cut, and maybe shorten, the section of cable between the cradle and voltage converter and put some kind of connectors on.

Do you have a source of reasonably priced power cables?

Oh, excellent. Thank you very much for that.

That's exactly what that part of the Advrider thread discusses. In short, the question which was it simpler using a mount & power cable between several bikes and either:

1. Add a 12v connector like a cigarette lighter, powerlet or SAE end or

2. Cut off the garmin voltage convertor box and use a USB connector with a USB (5V) socket on the bike.

So the power cable is a coaxial cable then!
