Echo Cruise Issue - Anybody recognize this part? (see pic)

Hi Toyota forumers,

The picture below is of the cruise control unit from my '04 Echo RS. The cruise has not been working since I bought the car ( previously enjoyed) from a regional Mercedes dealer.

There was only 15000K on it when I got it, so it is still well under warranty.

Toyota service tells me this is not a Toyota part and therefore can not service it. Can anyone tell me if they've seen this cruise unit on any other Toyota's, or for that matter, any other car? If you have cruise on your Toyota, perhaps you could send me a snap of it, so I can compare it to mine.

If you recognize the unit as not being a Toyota part, but an after market one, and know who makes it, please tell me.

I'm tearing my hair out trying to get this darn thing serviced, under warranty or not.

Thanks
Bill

BTW, the picture is of under the hood, looking from the front center of the car, back toward the fire wall on the driver side. The unit is bolted to the front-left wheel's suspension dome.

if its from toyota, it will say toyota some where on it, most likely on every plastic peice there is, they are good about putting their name on everything they put on their cars
