I earthed mine on the lowest 13mm bolt securing the dashboard, about a quarter of the way back up from the fuse board.
Hi,
can you share any photo ?
as the driver side is on the left... Probably it might not exist a ground bolt in the passenger side
Thanks
Haven’t got any pictures of it but if you watch this video you’ll get the idea. This is done on the W176 but there’s a bolt in the same place on the W177.

Hi sierramike,

my photo further up the topic is for a RHD UK car, where the fuse panel is in the passenger foot well on the left side, which is why I thought your photo may be upside down because the fuse layout is mirrored.

In mine you can just see my negative line with a croc clip on, going to the ground stud at the bottom left of the photo. It is outside and below the fuse panel.

In yours it may also be somewhere below the fuse panel, but more likely to the right if it is built the same way.

Hi Southwestwall,

Thanks

Hmmm good question. Bought them a long time ago when I installed this dashcam in my previous W176 A-Class.

I had a look and the original seller is no more, but they are 20A capacity fuse tap piggy-back standard blade fuse holders, widely available.

I did file the edge of the carriers slightly to get them to sit in the fuse slots properly, as the fit is quite tight and they had a kind of clasp down the edge joining the two halves of the body.

Those are 2 amp fuses in the piggy back holders, as they were to hand at the time and a fuse has to be inserted for them to conduct. The in-line cartridges have 1 amp quick blow fuses in ... the DR490L has pretty low current draw and better popped than sorry, though they never have.

Thank you, thought might be a long shot.



Just blade fuses come in three sizes, hence question, saves having to pull apart twice, take it they are "old school" standard blade fuses rather than the newer mini blades.

helpful information thank you for sharing. only thing is the fuse box has the incoming power pins on the left. so adding a spur fuse is good but it needs to be the other way around. as your picture shows the fuse isnt inline. so not protected. the tail want to exit on the right side

How exactly do I access the passenger fuse compartment?
I understand I had to remove the foot mats, then the floor carpet, but cant do that properly because there is a plastic piece (panel) covering the sills and going up on the door.
How do I remove that piece? Tried to pull it away from one side (from the bottom) but is still stuck into some hinge or some other restrain system and I dont want to break or rip anything. Can anyone explain how to remove that plastic panel so I can remove the carpet properly?

Thanks!

Anybody in the UK used Halfords to install a dashcam in their new A-class? Used them on a previous car and they did a fine job.
On my previous cars I've had specialist fitters install the dashcam (dual cam set up), have used Thinkware and Blackvue products. I had to leave the cameras in the car before, so on a whim, ordered a Nextbase dual Camera set up from Halfords, the order, delivery/collection was fraught with problems and getting a fitting date equally difficult as their e booking system didn't work. Anyhow, it went in this afternoon for a 2 hr fitting, 1hr for the front and 1 hr for the rear. Got a lift home as I wasn't going to wait that long, 30 min later, I get the phone call, sorry sir, unable to fit as we cannot locate a live free fuse. Went back and got a full refund.

So I'm now looking at another Blackvue set up. Blooming annoying as the Nextbase ones seem to pretty good for their prices.

Ignition Live turns off with the ignition, in old money if you turned the key to off. Nowadays in cars like the W177 it stays live for some time after exiting the car, about 30 minutes if I recall.

The other type is Permanent Live, which is connected to the battery bus and remains powered all the time. I used fuse slot 162 for that, as my dashcam has a parking mode and smart voltage cut-off to avoid draining the battery.

I’ve had a Nextbase 312GW for two years now and have only just found out it has parking mode. Currently have it hardwired into ignition live fuse 125. Obviously I’d now like to make use of the parking mode and from what I’ve read people have used fuse 162 for the permanent live feed.

My question is.... can I simply swap the piggy back over from 125 to 162 and carry on as normal? Or does anything else need doing?

Yes you can swap from ignition live to permanent live fuse with no issue. I did that to as the battery with parking mode on together with rear camera did not last very long. I have 522gw installed.
