    This hardware kit is what is required if you are having the dash cam installed with the ability to recored when the car is parked and turned off. It does what it is supposed to do so very difficult to say anything other than the dash cam is working great so this is what is needed. There are more than enough variety of connectors in the box ensuring that you will have the correct piece needed for the installation.

    Super easy to install. Granted I dug up a YouTube video for my specific vehicle but the process was simple. After installing the fuse taps (make sure they are the correct orientation), the camera fired right up. The harness allows it to record even when the car is off which was something I really wanted available. After reaching a certain battery discharge level, the camera shuts off rather than continue to drain.
    Running the wiring was the most difficult part. I’d recommend picking up a trim removal kit. They’re cheap but will save your fingers and potential damage when prying off plastic tabs.
    Various fuse taps are included so there should be no issues with different vehicle makes and models.

    I got this to be able to use the parking sensor/recording for my Viofo A229 Plus dashcam system. The package includes fuse attachments for every type of fuse used. Compare to what your vehicle has and attach to the power leads. The most difficult part is deciding which fuse to use – you want to stay away from vital systems like abs braking, engine cpu, etc, instead using something like interior lighting or the like. The other thing is that you need a multimeter or some other way to test the fuse socket to check weather the socket is powered with the ignition off or if it’s ACC controlled. You also need to determine which side of the socket has power because the adaptors have an orientation and have to be plugged in with the powered side out. So it’s a little finicky to get everything right but I’m not particularly handy and I was able to do it. It would have been nice if they’d used an easier connector then the crimp style but it worked.
    There is a switch included that allows you to select how low to take your battery before the camera system powers down. I set it in the middle and we’ll see if the vehicle starts after 48 hrs. You also have to set the system for parking before it will work. Lots of choices there so I’m going to have to see what works for me.
    All in all this works fine, I’m a little disappointed that it wasn’t included with the camera system. It seems like a bit of a bait and switch to advertise parking sensors but “oh yeah, you have to pay an extra $40 dollars for the part that allows you to use that feature”.

    Works as advertised. The parking mode on my dashcam now immediately kicks in (no delay) when the engine is turned off.
    The cord is sufficiently long for my vehicle (SK Forester) and seems to be durable.
    So far this has been money well spent.

    I recently upgraded my Viofo dash cam setup using the HK4 hard-wire kit, and it’s been fantastic. Installation was a breeze—even for someone with limited DIY experience—thanks to its versatile fuse tap options and clear instructions . Once installed, the unit reliably powers my dash cam and handles parking mode like a champ.

    One of the standout features is the adjustable low-voltage cutoff (LVC), with settings ranging from 11.8 V to 12.4 V. This gives me peace of mind knowing my vehicle’s battery won’t drain unexpectedly .

    Overall, it’s an excellent value—well-designed, dependable, and easy to use. Highly recommended for anyone looking to wire their Viofo dash cam directly for a cleaner install and smarter battery management.

    The Viofo HK4 Hardwire Kit with Fuse Tap is a solid choice for powering my Viofo dash cam. The installation process was easy, and the fuse tap made connecting to the vehicle’s fuse box straightforward. The low voltage protection is a nice feature that ensures my car’s battery isn’t drained. However, I needed to splice in my own longer wires because the included ones weren’t quite long enough for my vehicle. Despite that minor tweak, the kit works perfectly and is a great solution for hardwiring a dash cam. Would recommend it, but keep in mind you might need to extend the wires for larger vehicles.

    Its better to have too much wire, and have to cut some off or hide it away, then not enough.

    The Viofo Hardwire Kit is an excellent addition for enabling parking mode on your dashcam. Installation is straightforward and easy, especially with a trim removal tool to access fuse panels. The kit includes multiple fuse taps for compatibility with a variety of vehicles, and the harness allows the camera to record even when the car is off, with an automatic shutoff to prevent battery drain.

    Once set up, the parking mode engages immediately, and the unit works flawlessly for both front and rear cameras. I would recommend changing some settings in the VioFo app as well to get the best performance. The kit’s build quality feels durable, and Viofo provides excellent customer support if any issues arise.

    I bought this as an addition to a new car so i can have peace of mind when my car is parked.

    **This is an update to my review. Viofo sent me a message after this review posted and offered to send me a replacement wire harness. I agreed and had the harness in hand within 2 days. I removed the defective harness and installed the new one and everything worked perfectly. I still use Viofo exclusively because I think their cameras are quite good. This is the first time I had to use Viofo support for a defective item; and Viofo came through. Viofo really does make great cameras that are very reliable and at a good price point. It was nice to see that Viofo does back up their products when you need it.**
    I bought this as part of a package deal with a camera for a Christmas gift last year. I finally got around to installing the camera this weekend. I had an awful time getting ACC power to work; but after an hour or so messing around; it miraculously started working. I was never able to get battery (parking mode power) to work. So, after spending hours getting this to work; it stopped working after I buttoned everything up.
    This isn’t my first time wiring a car with a Viofo Camera and hardwire kit. I have done three of my own cars and two of my children’s cars. This is clearly a defective hardwire kit. I was surprised to get defective hardware from Viofo; but it happened. I’m sort of disgusted because now I have to buy another and wait. Viofo needs to improve their quality control with their supplier.
