    Penetrating the 'fire wall'

    My Easter weekend project is to install a decent sized power take-off direct from the battery to an Anderson plug at the back to run the electrics in my caravan. As a precursor I've already traced the wiring route all the way through the car and it seems reasonably easy although I need to remove a few trim panels. The only bit I'm concerned about is getting through the 'fire wall' between the engine compartment and passenger compartment. I've found where all the electric cables pass through, but it's a very full and inflexible rubber boot, with a 90 degree elbow in it, and it doesn't look like I can easily push a couple of 16mm2 cables through there. So, anyone done this on a DS, or similar vehicle, and have any tips?

    Here's a couple of photos of what I'm talking about. The first is of the wires disappearing into the rubber boot in the engine compartment, and the second is them coming out behind the passenger footwell. Thanks.

    when I have needed to get wires through firewalls I use a piece of cable sheef (like a bonnet release outer cable, push bike outa cable, that sort of thing), feed that troutgh for a start and then tape your new cables to it so they form a taper and gentlty pull them through, a bit of talcum powder will help ease them through.

    Do you need two cables to go through, I took positive to battery and earth to chassis

    Thanks for the suggestions guys. It turns out the rubber is moulded onto the wires at the factory, so no chance in hell of pushing any more cables through there! In the end I drilled a couple of new holes in the edge of the rubber to pass the new 16mm2 cables through. Feeding the cables through the rest of the car proved more difficult than I expected also, as all the cable ducts were pretty full, had bends and/or restrictions in them, and cable ties holding the existing cables to frustrate my attempts to push the new ones through. Got there in the end though, and my new Anderson plug is attached to the back next to the existing 12 pin trailer socket, and the caravan is receiving plenty of power without the cursed voltage drop! By the way Paul, I wanted to get the negative wire all the way back to the battery rather than using a chassis return because I've been told this is preferable for high current draw applications.
