Works Great, No Problems, Good Customizability
My previous hard wire kit for my Viofo A119 Mini v2 fried my car's battery, but this did not. That alone should make this a 5 star! My favorite thing about it is that I can choose how low I want the voltage to go before it will shut off power (keeping my battery safe). This is something that a lot of other kits didn't have, and it is especially good over here in the Midwest where you want as much voltage in your battery as possible during very cold days.The length was perfect for my car and I've had no problems with anything else. It did cost a bit more than others, but the voltage protection switching option alone makes it worth it. Overall, a great hardwire kit.

Great way to get you cam in and conceal the cords
Absolutely would buy these every time when installing a front camera dash cam. The installation was fairly easy and the cord was just the right size. A really good dash cam helps, but if you have a dash cam and you don’t like seeing the cord all the time, this is absolutely the way to go.

Don't buy this if you expect to hide the wires in your headliner. Otherwise it is a decent kit.
Very poor design. They put this huge choke coil near the USB-C plug.I found it pretty much impossible to hide the cable under the headliner because of this.So, I just decided not to use it at all.Wasted money again.Amazon read this and offered me a full refundBut I will likely just give the HK3 and the HK4 to the DI.Guess their customer service is working.

Good kit. Has all you need.
Does the job. Enough wire to run to rear on Pacifica.

Poor QC on connector end makes parking mode erratic
USB C connector intermittent connection to ACC power made the camera not work properly on parking mode. TEST YOUR SYSTEM FIRST BEFORE YOU INSTALL CABLE UNDER A PILLARS. This bad connector caused my dozens of hours of frustration believing the problem was due to an EV and not suspecting the cable. Viofo should have better QC on these cables, for in the forums, many had this problem. Viofo customer support attempted to solve and could not. Seeing as how this issue is common, it should have been the first thing to try.

This is a review for the HK4 ACC Hardwire Kit used with the A229 Duo
If you are planning to use the Parking Mode feature on your VioFo Dashcam, look no further for you have come to the right place. The packaging was pretty basic but the wiring insulation quality seems to be heat, cold, water and oil resistant enough to stand the extremes of most environmental experiences of a consumer's car. The kit comes with an integrated car battery voltage drop circuit with a four position switch that allows you to pre-set the battery voltage you want your dashcam to power off at. Bear this in mind as you choose a location for this switch. There was (more than) enough slack to find a suitable location for my switch (behind the glove box with double-sided tape). There is single wire between USB-C plug (at the dashcam) and the voltage dropout selector module. On the opposite side of the module has a small torroid (most likely) and three wires (Battery, Accessory and Common) for Switched, Constant power to the dashcam which enables parking mode to work on the dashcam. These wires are all the same length and the length of these wires was long enough to route to the fuse box of my Volvo XC60. The common wire has a pre-soldered spade connector that is very convenient for a quick installation but the red and yellow wires (battery and accessory) actually have crimped barrel connectors that you must interconnect with aftermarket fuse taps for your particular fuse size. This means that BEFORE YOU START YOUR INSTALLATION YOU MUST determine which two fuse locations you want to use, make sure you purchase (or order) the correct fuse tap size(s) and once said fuse taps arrive, check them to ensure they are the correct in orientation so you can install them safely without pinching them or bending them too far so as to damage the fuse tap wires. Remember also that you need to be able to actually close the fuse box cover after installing these fuse taps - they are pretty tall for their size, especially depending on the size of your fuse and there are probably six different sizes our there so do your research prior to starting the installation.This product was actually really easy to install, especially given the price. This is an excellent value for what is included and the unbelievable features the camera will have as a result. I highly recommend checking out parking mode if you own a compatible VioFo dashcam.One other thought: I installed the VioFo in my wife's car and I bought a FitcamX for my car - both have parking modes so I will be installing the fitcamX in my car today. I purchased the FitcamX hardwire kit and it was twice as expensive as the VioFo HK4 but the OEM actually pre-sized and pre-wired the Fuse Taps and pre-soldered the battery and ACC wires with in-line glass fuses BUT they don't have the voltage selector switch that you find on the cheaper VioFo. Once I get the FitcamX up and running, I will leave a review for that product on their page.
