Door LED wire

[n3oNx]

Can someone tell me were in the fuse box is located the wire for the LED doors? I wan't to know because I want to put a fake alarm LED than is only active when I close the doors. Alternatively it could be active when I take the key out of the ignition but I wire the LED to +12v of the radio and the +12v ignition of the radio also but when I take of the key (+12v permanent with 0v from ignition) the LED lights up but the doors lock opens :S
