Hi, this is an ongoing issue and I regret starting it but have received amazing help from members and about finished on the home run.
I have installed a dash cam that requires 1 live and 1 auxiliary power source.
My wires are now through to the trunk fuse box but I'll be damned (pardon the French) if I can work out which is the constant/live and which is the switched/
auxiliary fuse in this fuse box (pic).
In my frustration and some may chuckle at my stupidity, I connected the constant to the auxiliary battery next to the spare wheel(getting desperate) but the camera and the Blackvue power magic pro
powers down after a minute, ahhhhhhhhhhhhhhh. I am now watching 'Fear the Walking dead' and feel like I'm one of the characters.
If anyone can educate me on which fuse is live and which is auxiliary from the diagram/pic it would help me immensely. Thank you
