I'm trying to figure out how to wire up a dashcam to my Mk2.5(?) Focus (08 plate). I'm aware that cigar lighter and 12v aux socket are both permanent live and looking for a solution to getting ignition live.
I really don't want to have to pull the car apart or splice cables, and a couple of options fit that well: my preferred option below, or get Dave at autostar to provide the piggyback fuse and other bits to add some extra ignition live cabling to attach to.
My preferred option is to swap the fuse location to make the 12V socket ignition live - the info I've found so far is that it should be an adjacent socket, but I have yet to find a page on the web that actually states which socket to use.
From the manual, I have in the passenger junction box:
109 : Cigar lighter, rear auxiliary power socket
This is the fuse that I need to move I believe. Disturbed by the term "rear [...] socket" as I only have one in the centre console. It could be termed rear if some models have one in the glovebox, but I am aware that some have one in the boot!
So which slot should the fuse move to? Well, if adjacent then I have a choice of:
108 : Accessory to cluster (audio and navigation unit)
110 : Daytime running lamps ignition supply to lighting control switch
114 : Instrument cluster ignition supply, engine immobiliser
115 : Lighting control ignition supply
116 : Fog lamps
However, on looking at the fuse panel, only slot 110 is free (I don't have daytime running lamps).
What is getting me is I cannot understand how pulling a fuse and putting in another slot can change the behaviour of the 12v socket! I am not very clued up on electrics - I am guessing that the 12v socket is *NOT* wired up exclusively to the 109 slot but to multiple sockets, and it just happens that you get fuse protection with ignition live if connected to slot 110, and fuse protected permanent live if fitted to slot 109 (and for god's sake don't put a fuse in both!).
Am I remotely in the right ball park? Do I have the right shape ball???
