you said that the camera has a light for the license plate - did you pop the lens cover off the license plate light? does that camera fit in the space available?

i am not so sure about the current flow on the coils of those relays - the one with resistor shunts some of the current - the reason i am so picky about current is due to the fact that the coils are tapped into other circuitry not designed for additional flow of current... that is why i am using relay with 37.5 mA coil amperage. there is another one, for 17 ma, which would be better, but i was too lazy to find one... the 37.5 mA was bought at a Radio Shack... there is a spec sheet in previous posts...
