I hardwired in my new dashcam which required a switched and a constant on wire. I reviewed threads here and found some good info about which fuses to tap into in the rear fuse box (didn't want to go through the wirewall).

Problem is that the diagrams and photos were for SS models. ZL1s have a different rear fuse box. After messing around for a long time I found fuses that fit these needs and that you can insert a fuse tap into. See below.

One problem I found is that the parking mode doesn't work. The documentation states that the voltage when the car is off must be greater than 12.5V or it won't work. My voltage is 12.1V so no parking mode. Is this typical for our cars?

Fuse slots I used.
F19 - 10A is always on
F15 - 10A is switched.

What dashcam is this? I have a Blackvue DR750S-2CH, also hardwired to the trunk fuse box with their PowerMagic Pro that has DIP switches to set the voltage threshold for parking mode. Your hardwiring kit may have something similar, FYI I set mine to 12.0V with a 6-hour timeout.

?????
You say that<12.5V when the car is off eparking brake doesn’t work?
Want to see where you saw that.
Interesting, and may be a safety issue when the car is parked for a long time...
And when you say it won’t work:
-won’t engage?
-won’t disengage (should not be fun)?
-Will automatically disengage ?

Nothing to do with the parking brake.

Some dashcams come with a 'park mode' that has the camera on standby to record if it detects a bump.


Thanks for posting this, my fuse taps are supposed to be here today and planned on doing it tonight.

arpad_m. Same cam with Magic Pro. I was sent a trouble shooting sheet that showed which pins on the connector to the PoweMagic Pro were for switched and constant. I went back and looked at the sheet again and saw I had remembered it wrong.

It says "With parking mode switch on and engine off, battery voltage on yellow pin must exceed 11.8v or 12v for LED to turn on" I am sure the value is dependent on the way the dip switches are set. I had them set for 12.5v, no LED. I changed them to 12 and again no LED.

I guess I am going to have to contact BlackVue again to see if they have any suggestions.

Thanks
That was too enormous for the safety...
Sorry for the misunderstanding

The blackvue dashcams have a park mode. When the car is turned off the camera will go into park mode after several minutes and will only activate and start recording if the car is bumped. I had one in my Corvette. Great little camera and mine was hooked up pretty much the same way on the OP.

Okay, this tripped me up initially, but your battery may have been just a bit under 12V while you were doing the install (I swapped fuse tap locations at least 3 times, thinking I'd messed up somehow despite what the voltmeter said, before I realized the voltage was a hair too low for the kit to engage parking mode).

Try driving the car for a while with the dash cam installed and running in normal mode, and then parking mode should kick in properly when you kill the engine.

I can take a pic of the DIP switch settings on mine if that helps.

I was wondering about that. The battery was flat and I had to recharge it. This was how I discovered something was amiss.

I haven't really had a chance to drive more that about 15 minutes at a time, so maybe a good long run just to be sure (as soon as the rain stops). I was getting 12.1v on the constant wire. Setting the dips to 12v should work down to 11.8v according to the troubleshooting page I got from Blackvue. Who knows. I wasn't really interested in parking mode, so this isn't a bid deal for me in the long run, but as an engineer, I really can't let these things go.


I have all dips up except the second one which should be 12v and 6 hours.

Yep, same here. This is supposed to work if the permanent 12V fuse you tapped has the correct voltage. The PMP unit may be defective if it that's the case and parking mode still doesn't work for you.

Mine is 1SS. The dash cam is Thinkware F800 with parking mode. I got CEL using F19+F15 and F19+F38. While F19+F39 works.

Which fuses did you use? I got CEL on my 1SS using F19 and F15.

Great information, but you got the assignment backwards.

F19 switched
F15 always on

Too many adult bevies?!

I was not able to find a switched outlet in the fuse box in the trunk of my 2022 Camaro 1LT. And I didn't wanted to run the power cable for my Viofo A139 Pro dash cam to the front fuse box, as I am considering adding a battery pack later on which would be best in the trunk since there's so much space under the trunk liner. And I couldn't find a good solution for getting a cable from the interior into the space under the hood.

So I ended up partly removing the center console. I took off the two side trim parts in the front and the covers over the bolts in the back, and then it's just six bolts to remove. Then pry loose the sock around the shifter (I didn't wanted to remove the whole shifter knob) and you can lift the back of the center console up just enough to have access to the wiring underneath. There is a big multi-wire connector that has a thicker purple cable that goes to the 12v outlet (cigarette lighter), which only has power when the car is running or vehicle accessory power is on.

I was able, after removing some of the cloth tape that's wrapped around all the wiring, to tap with a crimp-on splice connector into that purple cable and run a wire through the center console, and around/under the backseat, into the trunk area. Since the cigarette lighter is already behind a fuse, I didn't add any additional fuse to the acc wire that goes to the dash cam.

I believe that the way my dash cam is powered, it always use the continuous 12v power to operate the cameras on, while the switched 12v is only used as a signal to know whether car is running or not, so it can go into "park mode" when the car is not running. So I'm not worrying about drawing too much current from that one cigarette lighter in case the 12v output is being used for other things at the same time, as the extra wire I put in won't draw much.

This may change if I end up installing a power pack though; I can imagine that that will be wired to charge only when the car is running. So maybe I will put in a relay to not pull too much power from the cigarette lighter then, we'll see...
