I just bought this from ebay..

I installed it last night and work great. No need to add any resistor or light bulb to fake out the system. I don't have any error message.
The unit is so small, and I just tie wrap right next to the connector. I used some old computer fan connectors so I didn't have to cut any wire.
Very happy with the item.
