Hello everybody, My 97' Z3 has an old Apline SEC 8027 alarm system that I would like to get out of the car and just put it back to factory. Any guidance on where to start, what to look out for and possibly a wiring diagram would be very helpful. I have never installed or removed a system like this, but i'm fairly competent in the garage, and will ask questions before I do something stupid. Thanks for any help.
