Hi guys, I would just like an advice where to find good ground in my Mazda 3.

I want to hardwire a usb port for charging a dash cam following this one..

I really want to avoid drilling for ground and prefer to use something that is already available. Since I'll be using a line from the fuse box on the passenger side, if someone could point out a grounding point I could use near it.. Thanks.

That is for a 2015 Gen 2  model. (The title does say 2012 - 2018)    The  OP  has Gen 1  2008.        However it could useful for Gen 2 owner, thank you.

No. It's for a 2015 generation 3. Wake up at the back there! :)

I realised it wasn't a generation 1 - there don't seem to be any videos about - but it's of more use than the VW video posted by the OP, particularly for anyone on the site using search.

lol the link i posted is good enough for people with basic knowledge about electronics i just bumped on this vid by chance on youtube. anyway my main issue is finding a good sweet grounding port for gen 1 near the fuse box. i came across a suggestion that there is one just under the fuse box. i am waiting for my kit to arrive and i'll look for it and maybe take photos to share. =)

Hi guys its been a while, I have done it. Took me a while simply because I thought I really didn't need it because my Eonon Head Unit have 2 USB ports which give sufficient power for my dash cam. But I was bored this afternoon so went on to put it. Took around 10-15 minutes to install.

Ground port @ Kick Panel Passenger Side



Piggy backing on no. 70 on the fuse box. (I forgot what it was for, but I know it only turns on with other electrics in the car's interior. - Which is what is advised.)



The whole setup..




Bought on eBay: (Cheapest I could find at the time.. and please note I had to add some additional wires to increase its reach.

Circuit Piggy Back Fuse Tap Mini Blade Fuse Holder ATM 12V (+ FUSE)

https://www.ebay.co.uk/itm/Add-A-Circuit-Piggy-Back-Fuse-Tap-Mini-Blade-Fuse-Holder-ATM-12V-FUSE/332557411372?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649


Lastly, I just tucked the dc converter module and ports behind the covers and that's it. Pretty simple.. Saves you from using your cigarette lighter for your dash cam and would allow you to hide the wires.
