vp 3.8 with gas new project vn s1 guted strip only
i was just wondering if there was a way to add a siren to the immobilizer in a standard vp with a bit of wiring and a relay seeing that the standard immobilizer sends a tone signal out when its engaged from the interior in sync with the flashing dash light

and im just asking out of interest

you should have a horn under the bonnet
it send a pulse to it so its not on all the time
if you add a siren to that wire ya siren will go on off on off

From what i hear the stock vp imob/keypad getup is easy to get around.

Though id be interesed in why mine has a key pad that unless you key in the code the engine wont crank, and the button on the key fob which you must press or the car wont get fuel/spark.

The key fob is a bitch especaly when it wont work, it nearly got to the point a few weeks back when i was about to run a solid 12v line straight to the fuel/efi realy just to get the bastard home, but then it worked rofl.

i haven't had that problem yet and by brainless thieves i meen 15 yo joy riders that barely know how to drive let alown bypass a immobilizer i know how do it as i lost the fob for my first race car and it was engaged and i wasn't sure about the rest of the wiring so i bypassed it :D

and lets be honest if the immobilizer isnt engaged all it takes to start a vn vp is a small flat screwdriver been there and did that when i lost the key to the race car :yeah:

I'm a bit confused about this.
Do you mean there's a separate horn from the normal car one, or are you talking about using the standard car horn for the "siren"?
