CAN bus (not PLC)

Ok, so I know this is a PLC forum, but I have a question about control systems so someone might know the answer.

Is there any easy-to-use, cheap can-bus controlled relay?
All it needs to do is listen to the can-bus and close on a certain (programmeble) frame, then close at another frame.

Has anyone heard of such a relay? (the application is to be used in a car, so the relay only needs to handle 12V)

//Thanks Markus

A quick google came up with these:

is this anything close to what you're looking for?

Hello,

If you find no other solution, one of these:

can easilly be programmed for that function.
