HID install
the multi function bulb is really just a bulb that moves up/down to change the angle of the light.

The cutoff shield in the projector itself moves up when the high beam is activated. The bulb does nothing...

with my setup it utilizes a halogen bulb for high beam in-which is about 1/10th of the brightness of my low beam hid's. i never use high beam and you really shouldn't need to, however if you do decide to keep the halogen high beam bulb you should wire it so the low beam hid's DO NOT turn off when you use your highs.

The one's I found on that "auction site" do not say they are aca's but are the same correct?

This is it. See the wires? They tap into your high beam. When you turn the high beams on, they move the light shield out of the way and you unleash the full light beam of the HID bulb. They are very easy to retrofit into the ACA housing. I will be posting my write-up on how to do this shortly. These Morimoto projectors blow the ACA projectors out of the water in terms of light performance.

If you look inside of the bulb hole, you can see the reflective shield inside. That shield moves out of the way when the high beams are activated.
Like I said, even the low beam performance of the Morimoto projector is MUCH better than the ACA projector.
The retrofit is so easy. You just unscrew 4 bolts from the ACA projector, remove it, then pop the Morimotor projector in and you're done. Then you just splice the wire into the high beam circuit and you're ready to light up the road to kingdom come.
Aren't the H9's HID? Or am I thinking of something else?
I would post a link to them but I'm not sure if that allowed. I don't want the CF gods to strike me down.

Look forward to seeing your write up on this.
YES, it is as simple and as easy as it looks.
There dozens of threads that address all the "issues" brought forth here as well as all the documented installation threads.
Only a few of the posts here actually address your question.
Surprises in life are fun, except when damage or injury occur.
My simple, surprise avoidance advice is the following;
1) Wear latex (or similar) gloves when disassembling/reassembling the lights. This will help you to keep ahold of the smallish screws, nuts and bolts during the process. Also help to keep body oils or contaminants from getting on the HID bulbs themselves.
2) Ensure you DO NOT contaminate the HID bulbs. This drastically reduce their life. (See #1) Body oils from your fingers can be far worse for your HID bulbs than any amount of on/off cycling.
3) Take your time and thoroughly clean and/or prep the area where you intend to mount your ballast. Those have been known to end up rattling around the bottom of the body work, yanking on the harness/wiring. Nothing good comes of this.
4) Disconnect the battery...
Aside from the electrical hazard live wiring presents it's good to remember that the same timer that turns off your interior lights, etc also will drop the light buckets, usually about the time you have digits or appendages in compromising positions...

HTH and Welcome to the Light!!
...then you should probably mention that there are more current or newer designs that have a (digitally, I believe) controlled wattage increase when the cutoff shield solenoid is activated, making the miramoto far from the top of the bi-xenon food chain.
Jus' sayin'...
