HK4 Hardwire Kit with 8pcs Full Set Circuit Fuse Tap, Type-C Port, for A329 series/A229 series/A119Mini2/A139Pro/WM1/T130 Dash Cam

This hardwire kit does exactly what it’s supposed to do and makes installing a VIOFO dash cam much cleaner and more professional. The biggest advantage is that it provides constant power without needing to use the cigarette lighter port. Once installed, the dash cam turns on and off automatically with the car, and parking mode works exactly as intended. The Type-C connection feels solid and modern, and compatibility with multiple VIOFO models is a big plus. I really appreciate that it comes with a full set of fuse taps. That saves time and extra purchases, especially if you’re not sure which fuse type your vehicle uses. The wiring quality feels good, and the voltage protection gives peace of mind that it won’t drain the car battery. Installation itself is straightforward if you’re comfortable accessing the fuse box. For someone with zero experience, it may take a bit of time or require watching a guide, but that’s expected with any hardwire kit and not a flaw of the product. Overall, this is a solid and reliable accessory if you want a clean dash cam setup with parking mode enabled. Well made, complete kit, and works as advertised. Easy 5 stars.

I used this VIOFO HK4 hardwire kit on my A229 Pro install and it’s been great. It makes powering the dash cam clean and permanent without running a visible USB cable to a charger port. The wiring is high quality, and the fuse taps and connectors give a secure, reliable connection to the vehicle’s fuse box. Once installed, the camera powers up and shuts down with the car properly, and parking mode functions exactly how you want without draining the battery because of the low‑current draw setup. Everything fit well and worked as expected with no weird voltage issues.

Update: Manufacturer sent a replacement that was installed and works great. As it says on the box, test it before running it behind the trim. Original: I have installed 5 of these now and they are great if they work. It signals the Viofo Camera to go into parking mode immediately after turning off the car or a little after to avoid capturing the door closing. However, 1 out of 5 is defective. After all the trouble in running the cable behind the air bags, the battery on this cable doesn't work. It shutsdown immediately and the light on the switch turns off. Tested and there is electricity going to the battery tap connector but defective cable just won't stay on. When it is working, the switch is good providing a custom level of how much to drain the car battery ensuring that the car can start. Although it taxes the car battery, it's cheaper to replace the car battery than a dedicated battery for the camera unless you have an EV.

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".

I used this for my Viofo A229 Pro Dash cam. Its very easy to install, It hides very well, The app that comes with the Dashcam is good enough for what I need, and its a good value for the money. It keeps my battey charged and clicked right into my fuse box in my 2000 Lexus RX350. It comes with 4 different size fuse connectors so it should cover whatever your fuse sizes are.

**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.

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.

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.
