~OKAY, WE'LL DRINK TO OUR LEGS!~

Speaking of weird poo poo, I did not have my dashcam in the day I was driving up I-95 and saw a car pulled over to the side of the freeway. As I came up on it, the door open, a man stepped one foot out, and an amazing parabolic arc of vomit shot out of his mouth. My biggest dashcam regret.

Are fuse taps sincerely the best way to power dash cams like this Thinkware F800 I picked up for my Mazda3? I'm new to dash cams and car electrical systems in general and so I was talked out of using them while seeking some hard-wiring advice from my dad. He insists my car should have "bodybuilder power points" just like the fleet trucks he used to repair and that I should seek those out as power sources instead of overloading fuse plugs.

So now I don't know which way is up. 99% of search results (videos, forum posts, reddit, etc...) that come up for "dash cam hardwire" use fuse taps - I have yet to find any guides suggesting alternative sources of power. And when I search for "bodybuilder power point" nothing relevant comes up unless I target the search for large trucks.

Maybe it was the fact that the fuse taps that came with the set I bought are rated 15A? After some further research it seems like it might be a bad idea to tap a 15A spot with two 15A fuses as it'd mean potentially 30A running through a plug rated for 15A? I can't find the exact amp draw of the F800 (just the 12/24VDC rating from the OEM cigarette lighter power cable), but for dash cams it seems 5A fuses should be adequate.

Just to clarify, the fusebox plugs I'm looking to use are both 15A and are marked as for the front and rear "accessory slots" (probably the two sets of USB ports the car has). I've confirmed that one always receives power, and the other only receives power when the car is turned on. These are required according to the hardwire kit that has a wire for "battery" and one for "acc" to support parking mode.

I checked the current draw for my Mobius (only relevant in that it has no screen) and a cheap Amazon 12V-5V adapter made for hardwiring car accessories with a bench power supply at 12V and a cheapie ammeter and it was ~0.2A on the 12V side. Likely you can put a 1A fuse in it for almost any single dash camera. .5A was the smallest I could find in blade fuses, but the rear camera has exactly a .2A fuse and hasn't ever blown one. I was also able to look up what each circuit was rated for on my VW versus the fuse in it so I didn't melt part of the fusebox like whoever originally owned my Prelude. There were circuits rated at 30A with 15A fuses on their loads but of course I went with the accessory jack fuse. The closest thing to those bodybuilder type connections in my car is a set of terminals distributing power to the various fuse sub-boxes but then you've got to run through the firewall and gently caress doing that for less than 1A.

he was a little upset at first but he was pretty calm once we actually parked and started to sort things out. i was a little worried when his only ID was a foreign passport, but he was insured and the policy was current so it paid for everything.

I scratched the Exige as a possible fun car because of the clamshells.

Both wrecks I've been in have been similar to this with cars turning into me across a stopped turn lane when they couldn't see oncoming traffic in the other lane(s). Except I was doing 30ish+ when I hit my folks. I'm obviously not a fan of obstructed view turn lanes any more.

this was my third front clam. as long as you are insured it will get repaired. the first two times my car was hit by someone while parked.

i just took it into the body shop this week to get an estimate for having a scratch on the rear left corner re-painted and, while I was sitting in the parking lot, a guy who worked at the shop who was moving around cars hit my car from behind and broke both clams by pushing the front of my car into another car (I hadn't put the parking brake on yet and I was pretty easy to move).

so I guess now it's gonna get a 4th front clam and a 2nd rear clam.

it's a really fun car but it's not easy to fix. the lead time on parts is usually "we only do one run of <part> a year and we can ship it to you in six months" so right now I am just driving it around with both clams busted waiting for parts to arrive over the next couple months.

I think I will probably take the current clams and try to get a fiberglass guy to repair them, then just put them in storage. I did the math and I can pay someone to $2000 to repair them, then keep them in storage for 6 years and that'd be cheaper than buying a new one from lotus.

Thanks for going through all that to provide some numbers for context. After I initially posted I managed to find a wattage rating for the dual-camera Thinkware setup. At 4.2W max draw, the amperage came out to something similar, around 0.35A lol.

Based on all this feedback, I figure there's zero issue to try and do anything but use the taps. I picked up some 5A fuses anyway and won't sweat this anymore.

Any front/rear dashcam recommendations for a classic convertible? I want it to be a semi-permanent install, so I don't have to worry about it getting stolen, and I'd really prefer to not replace the rearview mirror, since it's a "rare" mirror with map lights. The top stays down as often as the weather will let me, and both the hard/soft tops are a little leaky, so waterproofing would be a huge bonus

Not sure how long the cables would be, but you might pop one camera on the dashboard and another on the back bumper since you won't have any rear glass for a suction mount.

I've been looking at getting a new (used) car, but almost everything I see has always-on 12V power plugs and I don't want my dashcam to run 24/7 when the car is turned off and I forget to manually turn it on/off.

This might be more a car audio question, but has anyone had any experience with using the USB port on aftermarket radios to power a dash cam (presumably, they'd shut off when the car was stopped.) I think I can get around the USB/Dashcam having the problem of possibly treating the dashcam as a media storage device if I used a 'power only/no-data' USB cable.

You don’t want it hard wired? My cam is hard wired to an always-on connection because I do want it to run when the car is off (I just have to remember to turn it off when I pull into the garage), but my Valentine One is wired into a switched power source so it shuts off when the car does.

I'm only ever really interested in recording while I'm driving and I really didn't want to mess around with doing anything with the fuse stuff. I figured a radio with a phone charging capable USB port would be a possible solution since I was going to probably replace the radio, eventually, with something cheap but with some more features.

But if I'm eventually going to end up putting in a good enough radio, I should want constant recording, too. It's like the Gift of the Magi or something.

If you're replacing the radio, adding a dash cam into an on-only circuit is trivial (twist the power wire into the radio power wire when you install the radio), and even easier again if you use a fuse tap/add a circuit.

I finally made some progress on my dashcam install, but unfortunately I ran into a fuse tap issue. I need to install two fuse taps, one that's always on and another that receives power when the car is on. I've tapped one that's always on, but have run into an issue adding the other one.

For reference, here's the interior fuse box of my Mazda3:



I want to tap 11, which is currently empty and marked "Accessory sockets", but power on that terminal comes in on the right rail. This would mean I'd have to install the fuse tap upside down, so that the pigtail goes to the left. Unfortunately that lower part of the fuse box (9-11) is butted up against the railing the fuse box is mounted to. The fuse tap pigtail can't bend enough to accommodate it. What are my options?

That’s the problem, from what I can tell the fuse box seems to be divided into always-hot on top, up until 7 or 8, and the bottom three or four are switched-hot. 12 is a 7.5A for airbags, 13-15 aren’t available as terminals.

Is it a bad idea to tap into 20A or 25A fuses for things like seat warmers and driver side seat adjustment? If I found one switched-hot in that upper half, I think it’d be one of the higher-amperage terminals.

Oddhair

My tap came with two fuse slots, one for the original load and one for the added load, and they were pretty clear it's important to check whether you had it in backwards as it could leave your added load always on as long as one of the two fuses was installed and not blown. It's not typical I don't believe for the hot side to flop though I am no expert. If you pull the fuse and check between the right terminal and body ground do you find ~12V? If you were testing with one fuse installed then it may in fact be that they're flopped/your tap was "backwards" but it's hard to describe.

No, as long as you install the tap the correct direction, it doesn't matter what the original circuit was rated for. The supply side of the fuse (the one connected upstream to the switched +12V) is going to be a big bus bar through the whole fuse block. The wiring feeding whatever device you're talking about (i.e. seatwarmer) doesn't see any extra load.

On top of that, a dashcam is negligible load as far as a car is concerned.

This is a valid concern but only sort of. Backwards means the dash cam load is added to the fuse of the tapped circuit, but no further.
