Hard Wire a dash-cam Volvo V40 R-Design

Elad1962 · Dec 19th, 2016, 13:45

Hi Guys, I purchased a dashcam from Halfords and they cannot find a switched supply to piggy back the hard wire to, any suggestions? They say the 12v sockets are too difficult to access and they cannot find a switched fuse under the driver's seat or under the dash. Is there a spare switched fuse anywhere?

I used the cigarette lighter fuse (under the glove box) for my hardwired dashcam. I have a v70, but I would guess the fuse box will be in a similar position in your v40.

There's some good earth points if you remove the panel below the glovebox too.

The cigarette sockets in the cabin are switched in my car, only the boot one is a perm live.

Hi Crumpet, I am sure they looked there and could not find the 12v socket fuses, only under the bonnet and they didn't want to drill through from the cabin to the engine bay.

Hi,

Volvo support seems to think there is one there, have you had a good dig around behind the glove box?

Perhaps someone with a v40 could be more help but I would be very surprised if there isn't a fuse box on both sides of the bulkhead.

Apparently, he has checked and there are no spare switched fuses in either of the fuse boxes only permanent lives

Just piggyback off 12v socket in centre console

On that link I posted fuse 82 will be a suitable switched live. I used the nextbase fitting kit for my cameras, which uses a piggyback fuse to power the original circuit and then a new spur for the camera.

It doesn't have to be brand specific, it just takes one switched connection into two for the two fuses.

I know that would be the way to go but he wouldn't due to the complex access and breaking clips etc.

So number 82, the windscreen wiper fuses?

Yes, that should be a switched live, you can't activate the wipers without the ignition on.

I piggy backed the rear heated screen fuse for the rear camera and front wipers for my front camera.

There's suitable bolts for earth in the spare wheel well and behind the bottom glove box panel.
