There are two wires with plastic connectors under the hood with nothing hooked to them.
On a whim I plugged the lead for my GPS into one and it works just fine.
It is switchable powered. You can see the red wire with an inline fuse plugged into it.
Is it for accessory hook up as I used it?

It's for accessories. The red and white wire generally is used for winch switch power, there orange and white are for whatever you can dream up. The red and white wire is powered off the 10amp "drive" fuse, and the orange and white wires are powered off the 20 amp "accessory" fuse
