The device I received has no documentation. Also, there's nothing on the back where the wires connect to obscure the wire connections. Now I need to figure out how to cover it so water doesn't get into the connectors and short out or corrode it. There is no documentation on this site that could provide more information about it. Upgrade 1 star. The points I made are still valid. However, it's been working since I bought it, so it's another star. I also found that it doesn't fit the 7 pin to 4 pin adapter sold in various stores. Not sure because they are not of the same type although both are marked 7. Very disappointed.
