Also, there is a slightly more complicated one involving shaving the top part of switch to gain more travel in the up position and hence room for all four switch positions. Although, I personally didn't want to go through the extra trouble when this was so easy and didn't risk me dorking anything up.
All you need to do is slide out the small cover behind the inside handle of the driver's side door, remove the eight screws, and then unplug the lock and window electrical connectors.
Make a 3" long jumper from 18 ga. solid core wire and strip about 3/4" - 1" of insulation off one end and 1/4" of insulation off the other. The long piece of bare wire gets shoved down the hole on the right side of HugaBuga's diagram (there isn't enough room for the wire with the insulation on) and the short piece of bare wire goes down the hole on the left side. Push them both down firmly to make sure they attach to the connector. Test by pulling up gently. If they don't more, you've pushed them far enough.
Here is a picture of the JDM/EURO window switch of the driver side
The US Acura switch does not have the red/orange wire (pointed by the left black arrow), but you'll find that the wire is present on the other side of the connector coming from the door harness.
Just use a shunt to connect the black/yellow wire (pointed by the right black arrow) to the pin on the left were the red/orange wire is missing and voila! you'll have the AUTO-UP function available on the Acura
