Retrofitting Original Alarmsystem

Hello everyone,

I´m planning to retrofit the original Alarm System which is available with the parts number 1667847980.
Does anyone have the installation instructions or can tell me how long it takes to install the Alarm System?

My DS7 is a 2024, Diesel Model

Thanks everyone

Just curious.
Didnt your car come with the factory fitted Thatcham alarm ?
Or is it faulty ?

There is no factory fitted Alarm. Some specs. don´t have the alarm. >Performance Line Plus 2024 sold in Germany

Uk model exact same spec does ?
Then again the UK does having a lot of car thieving scums living here.
