Alarm wiring connections

Hi all, I have a 2007 M59 1.6HDI, I have recently been given an aftermarket alarm. The van has remote central locking but no remotes!

The alarm has central locking outputs of the type I have fitted to older cars in the past. Can anyone tell me where I can pick up connections for indicators and central locking motors?

Could I connect an indicator output from the alarm to the back of the hazard switch or does it having a bsi/canbus mess up this theory?

I have read around and found the central locking motors can be picked up on the connector mounted at 45’ on top of the bsi.

Any help appreciated

Dave
