Power for Dashcam and Mysterious Fuse

[GDM123]

Evening,

Have seen the below post with regards to power for dashcam but i am looking to wire into the fuse box. This was relatively easy on my Corsa D i just tapped into the heated seats that the car did not have and i got power. With the Astra i have found that i either can only find constant lives or dead feeds. I am wanting to tap into a power source that is live when the car is on accessory but when i have tried tapping the 12v socket at the front it will not power anything unless it is physically plugged into the 12v socket. Any ideas?

Also the fuse in question is fuse 18 in the glovebox all the handbook says is "logistics" any ideas what this actually powers as do not want to be tapping into any delicate/important/safety related systems.

For the records my car is a 65 plate Astra j SRi 1.4 (B14XER).

Thanks in advance for any replies.

Maybe you should use fuse 6 or 7 and adapter:

Yep what Jerry said worked fine for me

I tapped into the rear of the 12v and when you have the key acc it works without issues.
