Help - How to bring '+' power through the bulkhead
 

Hi All.
Not sure where to go with this,

I need to bring '+' power on my 2019 XC40, into the car from the main under bonnet fuse box but cannot see a way through the bulkhead. Anyone got an idea or who has tried this before?

I have picked up '+' from the fuse box and then added a new temporary fuse box (I will remove it when I sell the car in a few years) the added fuse box gives me fixed connections to be able to safely add a screen camera and a fixed charger for my phone.

Thanks in advance.
Regards

Would it be possible to connect to the fuse box in the passenger side footwell?

Hi 844PHW. Thanks, yes I could but in order to complete the job correctly I always (with other cars) add an additional fuse box which is under the bonnet. It is a simple set up with a 1 point fixed live and 4 separate fused terminals I use for phone charging, Screen Camera and Traffic Alert device. All of the cables are bundled and taped together which is why I have always run them through the bulkhead on previous vehicles. I will have a look and see if there is a way to both pick up an Earth under the passenger seat as well as finding a way of 'trunking' the cables to the under dash area.

Thanks again, regards.

On the other models there is a rubber grommet just under the passengers left foot under the carpet and thick foam pads ..

Thanks Clan. I will have a look.

I just noticed on the XC40 accessory web site that there are no longer any accessories which need a wire running back into the car so you may not have a hole , worth a look though ..

Thanks again. Worse case I will just remove the glove box and look for a safe place to send a drill through the bulkhead myself sealing it with a new grommet.

If you haven’t completed this job already, there’s a good constant live from the main feed to the under seat fuse box.

This comes through the bulk head from the battery and terminates with a usual ring terminal at the fuse box. Adding your own ring to that termination would allow you a clean + feed for your requirements.

Visible after removing the sill trim, as in the first photo.

With the seat raised and carpet bucket moulding removed, it becomes clear. Fuse box terminal is just under the white foam block at the bottom of the second photo.

It would save you drilling and provide plenty of space to tuck away your own additional fuse box.

I’ve got one of those socket sets. They are amazing and I use it every single day....

I took delivery of my XC40 Inscription Pro T4 just before the lockdown so I’m not getting much use from it.
I’m interested to know whether you solved the electrical feed problem and where you found to mount your dashcam?
I’d used a dashcam for a couple of years but found that the big plastic dome behind the rear view mirror left me nowhere to mount my camera without blocking my view.
