Wiring alarm into central locking

Media999

Need advice on fitting an alarm.

At the moment is hooked up to power and shock sensor.

Seems to work fine. Arming ok. Alarm going off when shock sensor activates.

I need to know exactly how it connects to wires from central locking pump in door. Is it just a matter of splicing the wire and wrapping alarm wire around it?

Thanks in advance

What make/model/year is your car and whats the make and model of the alarm?

I think i have it sorted after a bit of research. Just need to find wiring now.

It has to be connected to acc/on so alarm disarms when car is on.

Which basically means you can hook it to anything that only works with the ignition switched on. i.e cigarette lighter

I wouldn't be using a cigarette lighter wire for the ignition feed wire off an alarm, your better off running it direct from the ignition wiring @ the fusebox and using an igniton "on" wire as opposed to acc.

Central locking also varies widely, different cars use different systems ie positive/negative/2stage/vaccum so make sure you know exactly what your cutting before you do it and try to solder & heathshrink when joining cables when you can.

Its a 2000 A4 b5 im wiring it into.

Diagram on Alarm has white wire to Ignition on

Ignition on is just a picture of an ignition.

Picture attached. Ive no scanner just had to take photo.

Yeah that should be connected to your actual ignition on wire not a cigarette lighter feed. Here's some wiring info I have on 99/00 A4's, I'm not to sure if your model may be different so triple check all wires with a multimeter before cutting anything

12V - red/ignition harness
starter - red/black ignition harness
Ignition - black|ignition harness
acc - yellow/black ignition harness

cl lock - brn/gry or red/brn drivers kick panel
cl unlock - gray/white drivers kick panel - *Negative lock*

Door trigger - brn/yel & brn/wht - Driver side A pillar leading to kick panel
Boot pin - white/black from rear switch into drivers side isll
