I have a 97 Outback sport, and I'm not sure on exactly what security features I have. I have the keyless system and the lights flash but no horn chirp. I have noticed a black box in the engine bay that has a 4 wire connector coming out of it and it has a loop of wire going to two of the the wires coming out of the box. Its mounted on the firewall wall, on the drivers side. There's another 4 wire connector that fits into the box's connector. plug it in, and the starter is disabled. My question is: is this the immobilizer for the alarm system, and if so, how do i get it to work? Right now i have the loop in the connector in, and I use an aftermarket fob for the keyless entry, if that helps (although the factory fob does not make a difference in its working).
