I mounted mine in the trunk and put the IR on the cabin "Roof" alarm sensor...

Can't find my camera to take a few pictures...

Search Walmart, Kmart, Target, Sears, SamsClub, Bestbuy and CurcuitCity.com and search for "Converter Box", I bought the cheap one from Walmart it was the smallest!

Passive is both analog and digital signals, so this is the one you want, but then again we can recieve analog signals on our TV tuner.
