Review: Reliable Hardwire Kit for Clean Dash Cam Install - 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.
Review: Needed for parking features! - Works as it should and is not overly difficult to install, although I would say it took me like 30 min to install. This is very necessary if you want to use all the parking features with the dashcam, unless your cigarette lighter socket remains hot even with the car off. I would recommend because it also frees up a slot for a charger.

## Questions & Answers

**Q: Camera stops when engine is off**
A: The yellow ACC wire senses ignition status to switch between driving and parking mode. If the mode doesn’t change, ensure the ACC wire is connected to an ignition-triggered circuit and parking mode is enabled on the menu.

**Q: Camera stops unexpectedly during parking mode**
A: This usually occurs if the battery reaches low-voltage cutoff or the parking timer ends.

**Q: Camera keeps recording after turning off the engine**
A: Confirm the ACC wire is correctly connected to an accessory circuit (not constant power).

**Q: How to install the dash cam hardwire kit?**
A: Connect the red wire to a constant power source using a fuse tap. Connect the yellow wire to a circuit that only has power when the ignition is on (ACC). Securely ground the black wire to an unpainted metal point.

**Q: Does hardwire cable have low voltage protection function?**
A: Yes, the hardwire kit features built-in low-voltage protection. It automatically cuts power to the dash cam when your vehicle's battery drops to 11.8V (for 12V systems) or 24.8V (for 24V systems), preventing battery drain.﻿

### ⭐⭐⭐⭐⭐ Easy to install; works as expected
*by C***G on August 21, 2025*

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.
