There are two fuse boxes in the cabin area does anyone know if any of those fuses have a permanent live?

Would it be ok to wire/piggy back dashcam into alarm fuse as presumably that's a permanent live but wondering if the voltage change will set the alarm off.

Thanks

 

I hard wired my Blackvue dash cam to my fuse box last week but i used the fuse box in the boot. I also used 2 piggy back and use a volt meter pen to find out which fuses were permanently live and which ones weren't. Then i used that the fuse chat sheet to find out which fuse is what.

This mite help you little:

 

The guy from Blackbox my car did a wiring video on a C400.
