Guess it gets confusing as they are different circuits.
Is this the one I bought from you?
Yes this is the earlier "Basic Alarm" (as Volvo calls it) without the remote locking feature. It works by itself without remote locking, but if you want remote locking as well then you need to add the remote locking unit which connects to the green plug behind the glove box, which I believe you have done.
"Basic Alarm" relay is easily identified from "Volvo Guard Alarm 1" and "Volvo Guard Alarm 2" relays by the lack of green connector on the top of the relay. The green connector on top of Volvo Guard Alarm 1 & 2 relays is for additional alarm sensors such as glass break sensor, ultrasonic sensor and/or tilt sensor, none of which can be fitted with Basic Alarm.
