Negative triggered 12v Flasher circuit diagram

Hi all,
Need a little help in building a cct that will flash my indicators 2 or 3 times when a 1-2 second Negative is applied. Basically I have built a remote control unit to lower and raise the doors on my Z1, then lock them.
**broken link removed**

I will be wiring the central locking onto the receiver and the central locking relay that uses negative supply to open and close the locks. Ideally I would like it to flash twice to lock and once to open. If I need to build two CCT’s that’s not a problem, or even a kit would be great. Any help would be much appreciated. Thanks

Any ideas anybody ??

Why did you not use a standerd remote lock with that built in?
