My you are a young whippersnapper then, riding GPZs! I now know why 'cold and dark' can be scary... You then must have red hair when you also talk about "Tomorrow" (Annie). Are musicals in your blood? Just kidding...
So back to yer problem, watch some videos, get the wiring diagram (real simple to read), get out the voltmeter and then dive into the wiring of the beast. Again, real simple.... really.
Good Luck!
