Anti-theft car alarm w/cut off where?

[mezc]

Pink wire at IP, can I use this with a relay 12V 40Amps as starter cut off?


I was thinking to install an alarm with a relay to open this pink cable on the Injection Pump as another option to secure the truck while park in public places.

Anybody did it here? Any ideas?

I prefer no to use a battery disconnector


what is this pink wire?

I like the idea; however, rather than alarm controlled why not install a hidden cutoff somewhere in the truck.

Actually I first bought a 10Amp switch to installed aside the voltmeter with a trick label saying “fog lights”, like I have in my jepp.

But then I was thinking on the stereo and an alarm system will protect both.

I have the common cucv key.
