How the heck do you hook up the factory antenna for an aftermarket radio install?  I've heard 4 wires have to be hooked together, and I've heard two wires hooked together, but neither of these combinations worked, unless I was hooking up the wrong sets of wires.

From the back, I can get the antenna up by jumping a hot to either the red or green wires, and the blue / YELLOW wires - grounding the BLACK / YELLOW.  I can get it to go down by reversing the polarity of the blue / YELLOW and BLACK / YELLOW, so I know the antenna works.  I could use relays to accomplish this, but the motor needs some kind of "cut-off" to stop it from continuously running in the chosen direction, or so it seems (I removed power after a couple of seconds of limit travel so I wouldn't burn out the antenna motor).
