Kill Switch ?

[baldricks mate]

Hi All, I don't have an alarm in my 1997 Z3.
It has the key induction loop on the ignition barrel of course but I want something more.
I've settled on a big bright red F-off steering club lock and a kill switch.
Most thieves are fundamentally lazy, wanting something for nothing IMO., so you make it as hard reasonably possible.
The hidden kill switch is low tech and works well in my experience.
However I am unfamiliar with Z3 electrics being a new owner.
Can anyone in the Brains Trust advise what wires I'd be searching for to use as a hidden kill switch circuit?
Thanks in advance

I dunno mate, my car does that all by itself, sometimes when I least expect it..

Hello - I can't offer any direct advice but if you can read wiring diagrams then this may help:

Yes, I can read a diagram but phew, 347 pages! It is, however a place to start so thanks!

Do you want it to turn over and not start or not turn over at all ?..

You need to pick a circuit that you want to cut and splice in a switch that is mounted in a secret location.
Most of us have the BMW alarm or a substitute that disables the starter circuit, most alarms do not want to disable the ignition circuit for a variety of safety reasons.
So, advice,
1. Install an alarm and do it the right way.
2. If you proceed with the switch, disable the starter solenoid trigger (12 volt in start only).
