3100V 1-Way Security System

I fitted it into my 205 gti when I did an engine conversion as I had the dash already out.First off. And the instructions do not mention this. If you want some of the extra functions to work such as interior light illumination or additional accessories like windows go up when you lock. You will need relays.Be careful where you earth the alarm. When I terned my lights off the alarm would go off as I earthed it to the same earth block as the headlights. So I moved it, problem solved.Better instructions are avaliable for a different alarm (which is actually the same) type in “avital 3100 instructions” into Google and it’s the same alarm but instructions that actually are helpful.Other than that it seems ok. I’ve only driven the car twice and it was ok until I tried to tern the lights off then tern off the auto lock and alarm chirp then all hell broke loose.People say the alarm is quiet. It is not quiet at all. The install is quite involved you will need a multimeter and a box of electrical connections etc, but would be the same for any alarm. To sum it up for the price it is probably as good as any other and the remote is quite nice but it is very chineese. I would recommend installing a hidden switch on the siren earth that will stop the alarm sounding.
