its a 79 bmw, i havnt got the one that came with the alarm even mounted yet but i will put up by the battery facing down, but i tried attaching the siren that came with it, connected it to the brown wire and grounded it, but i didnt get any noise from it.
I accidently pulled out the door unlock/lock plug from the brain and now i hit a button on the transmitter and it gives me the timed out beeps. I tried resetting it, it gives me 2 beeps when i reset it. and still doin the same thing
