There are small numbers on both ends of the wires.
3 is positive, 1 is earth and 2 is unused.
I presume you have a power adapter for your GPS, don't connect these wires directly to your GPS unless it's designed for 12v input. I have a Garmin bare wire power supply (fused), but there's also a Garmin part that is a direct USB connector with no power supply inline... Be careful.
The connector is connected via the ignition circuit.
Cheers.
