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.
Review: Easy to install; works as expected - 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.

## 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.﻿

### ⭐⭐⭐⭐⭐ Works great
*by B***N on September 28, 2025*

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.
