I want to fix a second cigarette lighter socket in my Peugeot 207 (2009). The existing socket turns off when the ignition is turned off. This fine for my navigator and the odd top-up for my mobile phone. I need to use my laptop for work (not while I’m driving!) and I’d like to charge it while I’m driving and let it continue to charge when I park. I’ve bought a new cigarette lighter socket and I’ve fixed it in a panel in the passenger foot well. Wiring the earth connection is easy but the live isn’t. My laptop needs about 8 amps at 12 volts (I can buy a converter to match this to supply needed for the laptop). I can’t find any accessible wires near to the fuse box to piggy-back a connection because everything is wired to tightly. I think that my best bet is to run a wire (protected by an in-line fuse) directly to the battery. My problem is getting a wire from the passenger compartment in to the engine compartment. I could drill a hole and protect the wire with a grommet but I can’t find anywhere accessible. Does anyone have any ideas where I might drill (without hitting a servo or other vital part!) or whether there is an existing, accessible place?

Could piggy back off constant live at ignition switch,fit an in-line fuse and wire it to your 12v socket

Thanks bustedknuckles for your suggestion. A good idea. The fuses are difficult enough to get at even to change a fuse. All the clusters of wires in this area are very short with, I thought, little chance of finding enough space to fit one of the blue, piggy back connectors. Do you think that there might be a chance of the forked slide of the piggy back connector cutting a few of the strands of the fairly heavy wire to the ignition switch and therefore reducing the load capacity of this vital connection?
If I wanted to run a new wire (just a live feed) from the passenger compartment to the engine compartment, is there a place in an existing opening through which I could thread a wire, or can you suggest a safe place where I could drill a hole?

Go through any existing wiring harness grommets at bulkhead with your wire .

Thanks whittingehame for your suggestion.
On the engine side of the bulkhead at the right, behind the battery, there is a large, black, plastics plate with a bundle of cables running through it. There's no chance of squeezing another cable through the same opening in the plate because it's so tight and sealed. Thinking that it was made of rubber (or a flexible plastics) I tried to prise the place off and it just cracked. I'm afraid of drilling a hole through another part of the plate because I don't know what I'm going to damage on the other side. I suspect that this is exactly behind the fuse holder assembly so a steel drill hitting some live wires and earthing them from the drill could be disastrous! Which existing wiring harness grommet do you mean? Would it be possible for you to send to me an image of the location of the grommet?

Unfortunately I dont have a picture of your cars engine bay or are aware of the layout so unable to help . On a lot of cars it was often possible to put a welding rod or similar through where one of the wiring looms would enter the cabin and attach the wire to pull through .Obviously yours is different . Another possible route on some was where the bonnet catch release cable entered . Sorry cant help further on this .

Thanks whittingehame for spending the time trying to help. It's bucketing down here but when/if it stops I'll take an image and send it to you. (Can .jpgs be attached to this messaging system?) The engine compartment of the Peugeot 207 Verve is packed! There are few places in the engine compartment where the bulkhead can be seen and even fewer for access. The passenger side foot well is accessible from the inside but there's a servo tank (I think) on engine side so it's not a good place to drill. The bonnet release is a good idea. I'll see if I can use the aperture for that. Thanks again.
