on fitting an alarm to the car i tried to find out what wires locked and unlocked the doors. I did this with an earth instead of a live but i still think ive blown something.

Now when i open the drivers dor with the key, the others wont open and the deadbolts on.

Also the car wont start unless i pull up the door lock on the passenger door.

Now i checked the fuses, the ordinary standard fuses that is, now im thinking there must be a separate fuse somewhere or maybe a Central Locking "BRAIN" ?

Has anyone any suggestions please.
