Some time ago I got an extra auto-down module from someone off this forum, I don't recall whom. Here's what the module looks like:

And here it is wired into the driver's door wiring:

Wiring it up was a matter of tapping power for the autodown unit into the main power input to the window switch module, which is the thick brown wire in the middle. The harness tan wire gets cut and the switch side connects to the autodown module's gray wire, while the passenger door side connects to the module's brown wire (the one that isn't the module's power wire). Finally the autodown module's dark blue wire taps into the harness light blue wire.
I hooked it up and tested it out, and it works perfectly!
