Bit of help here would be very much appreciated,I'm in the process of wiring in my dashcam I was going to use the 12v socket in the top tray but its permanent live and I want a ignition live so I decided on fitting another socket in the top tray on the opposite side, I've ran a twin wire down to the fuse box, what I want to know is which ignition live fuse to piggy back off and where to earth it,would it be ok to run a wire across underneath the tray to the existing 12v socket to earth it and if so which is the earth (3 wires red brown and grey I'm guessing brown ?) if this is not a good idea any thoughts on where to run it
many thanks
