What are the THREE wires for?

[BradB]

In a EzCan II, what do the THREE wires do?
SOLID COLOR ......?
BLACK....GROUND?
COLOR W/BLACK STRIPE....?

I am choosing the circuit to be an accessory circuit.

I assume one of these is ACCESSORY/IGNITION power?
Is the other full time power?

Still struggling along here. Thanks for the help.
