Slick idea, I might end up doing that if I can't get any information out of Denso -- I got a reply from them today:

Best regards,

So I went to www.densoaftermarket.com, and it looks like they don't even list HVAC units. When I went searching, the website said "If you are looking for a part not listed here, contact your car manufacturer's local service dealer". Looks like I might need to roll on down to the local toyota. There's one down here I know people at, but they suck so I don't think I can weasel info out of them.

If at all possible, I'd like to try speaking to the car's hardware directly w/o tearing apart the factory HVAC control unit, but we'll see.
