(update): fixed the issue. Benz's 12v was hard to find. Most 12v powers auto turn
off after 90min.

Parking mode didn't work, it doesn't turn on when ignition is off. Yellow wire checked, constant 12 volts.
Again, received a lemon?
Update: figured out the problem and is working now.
Update (04.18.24): something is still not quite right, measured voltage 12.4v from the module input but the camera after 1hr or so shuts itself off. Measured battery voltage is12.4v. Therefore, it shouldn't cut-off the power, not sure what's going on.

5.0 out of 5 stars Great Hardwire kit for dashcam
Reviewed in the United States on June 30, 2024
Just purchased the VIOFO A229 Pro and I wanted to make use of the parking mode, and also wanted reliable connections, so I went with this all in one always-on USB-C kit. I had selected my power seat for the constant 12 V source, and eventually the 12V Power out (cigarette power outlet) as the switched source. Once I had these properly identified, the camera was able to switch between 2 channel normal mode with the engine running and then parking mode with the engine off.
Be sure to test out your switch source- some cars like Toyotas that allow the circuit to stay on until the door is opened will actually always have power present across the fuse (like the moonroof in my case), and may throw off the selection for your yellow wire source, so you still need to test. Once I switched the fuse-tap to the 12 outlet fuse, the camera switched between modes properly. Easily can recommend.

4.0 out of 5 stars Works Well with A229 Pro but Fuse Holders are Difficult to Crimp
Reviewed in the United States on May 6, 2024
I installed this hardware kit in my Subaru Forester to use with my A229 Pro dashcam. It replaced another hardware kit from a different manufacturer, because I needed VIOFO's kit with a USB-C connector.

Installation was mostly straightforward because I already knew which fuses to tap into, but the fuse holders were difficult to crimp to the wires. I couldn't crimp them with pliers, so I ended up buying a crimping tool at Home Depot. Aside from this minor complaint, I've been very satisfied with the kit. I'm hoping it'll be compatible with future dashcams from VIOFO.

Wanted to hardwire for 2024 Subaru Crosstrek and hid all wires from driver and passengers. The dash cam did not come with the needed wiring for this, just a wire to plug into 12v outlet.

Did have trouble with testing and targeting right car fuses to use. At first, I had both wires tapped to unused fuses that both operated all the time (ACC), so unit would never go into parking mode. So I became increasingly concerned about battery drain. Finally retested fuses with my multimeter and moved ACC fuse tap to another fuse and voila, it began working exactly as intended. Note: Email support from Viofo was unclear on this scenario and recommended various troubleshooting tips in the wrong direction.

Had a little trouble crimping the wires to the leads. Bought a tool from Lowe’s for this, but would have been nice to know on the front end.

I also installed the rear camera upside down when attaching it to the glass, but the dash cam apparently understood and self-adjusted for this.

I was reluctant to use parking mode at first due to concerns that the dash cam might drain the battery. But two things worked out to offset. First, the wiring to the fuse box included a little rectangular power supply regulator that allows you to adjust at what battery level the unit will self-deactivate. I set this to the highest setting. Second, with the wiring fixed, parking mode activated automatically and I was able to configure the dash cam to shut down after 1-2 hours of the engine being shut off. I haven’t tested the event-based recording function so far. I bought the dash cam mainly for a new teen driver and insurance reasons.

I would avoid these with a 10 ft pole. Seriously, just don't buy it. They look amazing, the wires are nice, the kit seems great but I bought 2 kits and neither send power to the camera. My buddy and I (electrical engineers if that means anything to you) tried everything to try to get 5v out of the wiring other than tearing the kit apart beyond repair. Beyond disappointed as I bought this from viofo for the viofo dash cams I purchased (A229s) and now going to have to figure out how to wire it with another kit. I will update with another product you should buy if I find one that works. Seriously just don't buy this, not worth your time and the hassle.

Plenty of length and very easy install. Came with fuses, but be sure to read the instructions and have load side on the far side of the cable. Works with the A229 Plus that purchased with it. Now I get parking on both front and rear cameras.
