Hi all quick question there is a big thick red wire in the wiring loom on the left hand side of my car at the back near the lights what is it for. The end is cut and attached to nothing the reason i ask is i am attached a 12s towing socket for my caravan fridge an battery (not the one for the lights) is this a factory power cable for towing or something else

how thick would you say it is??
is there a wire the same coulor and thickness attached to the live on the battery?
if there is it mabie an old amp power cable, mabie form the last owner of your car.

It could be worth seeing if there's actually any volyage on it, you never know your luck!

Hi its about 3 or 4 times the thickness off the other cables that control the lights but it looks like it came out of the factory with it havent checked battery yet but will have a look

Could be power for a caravan socket? Does the car have any sign of a towbar having been fitted in the past?

hi there is no sign of a previous tobar on the car i also cannot find a gap in the bulk head to feed a cable from the battery to the 12s charging caravan socked at the rear

Hi If its like my D8 estate there is in fact a grommeted hole almost dead centre of the passenger`s footwell, Its not easy to find unless you know its there...
You need to lift the carpet, and the sound insulation under the carpet and about half way between the floor and the passenger parcel shelf you should find a nice sized grommeted hole. It means a lot of trim /clips etc need to be removed to get at tho... so you may wish to make your own hole and grommet that instead. I`ll try to take a photo if you would like an idea of where it is from the the engine bay side.

Hi

That woulds be great i will have to take up the front carpet then and have a look if you managed to get a photo that was also be very helpful thankyou for that info it should prove very useful

The view from engine bay showing my amp cable routed along the nearside inner wing bulkhead i routed it down the rear of the servo. I dont have abs so the alarm siren you can see is roughly where your abs would be I think.

The view showing where the grommet is in relation to the brake servo. If you stretch your arm in and feel for the bulkhead roughly where a passengers left foot would rest you should come across the rubber grommet

Finally the view showing where it is

From inside the car the best way i can describe the location is as above.. you will see/feel the curved wheel arch and then about an inch in and about 6 inches up from the the floor pan on the flat section of the foot well is where it will roughly be.
