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 used this VIOFO HK4 Hardwire Kit on my 2025 XLE RAV4 and installation was seamless. The full set of 8 fuse taps made connecting everything straightforward, and the Type-C port adds extra convenience. The kit feels well-made and reliable, providing a clean, professional hardwire solution for my dash cam without any issues.

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 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.
