Sure... Easy one. Just put it up to a 12 Volt car battery using some probe wires... Done it plenty of times. Don't forget to ground the unit to the negative side of the battery if there is a provision for it....like a 3rd wire for ground.
Obviously, This should go without saying..Check the Wiring diagram first so you know what wire is what for each color wire...
I don't know what each color wire is off hand without looking it up...but I can only guess that they are +positive, -negative and GND (Ground). Usually a brass terminal is a GND Ground....so just check what all the wire colors are anyway..
