The biggest advantage is that it provides constant power without needing to use the cigarette lighter port.

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.

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. ## Features - 【Fuse Tap Not Included】Note: The installation of the harewire cable requires the connection of the circuit fuse taps. If you need the HK4 with 8pcs full set circuit fuse taps, please check the ASIN B0CHDXPGP1. If you need to buy circuit fuse taps separately, please check the ASIN B08SJZJCV5. - 【24 Hours Parking Surveillance】When the engine is off, HK4 hardwire cable provides continuous power to the camera, any collisions, event will be recorded. - 【Low Voltage Protection】HK4 hardwire lets you set a voltage cut-off value with 4 options, when the voltage of vehicle’s battery drops to the cut-off value, it will stop powering your dashcam, thus protecting your battery from discharge. - 【Automatically Switch Parking Mode】With ACC detection, the dash cam will switch to parking mode automatically if the vehicle engine is off. The dash cam will switch into normal recording when the vehicle engine is on. - 【12 / 24V Compatible】HK4 ACC Hardwire cable connects the camera directly to the car, truck, bus, SUVs, or big rig for continuous power, accepts voltage from any type of vehicles runs on 12 – 24V. - 【Installation】The hardwire cable length is 13.1ft (4m). The red battery cable should be connected to constant power. The ACC yellow cable should be connected to ignition. The Ground cable should be connected to vehicle body.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Hardwire Kit for Clean Dash Cam Install *by A***Y on February 7, 2026* This hardwire kit does exactly what it’s supposed to do and makes installing a VIOFO dash cam much cleaner and more professional.

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. ## Frequently Bought Together - VIOFO HK4 Acc Hardwire Kit, USB-C Hard Wire Kit for A329/A229Plus/A229Pro/A119Mini2/A139Pro/WM1/T130 Dash Cam, Low Voltage Protection for Parking Mode - VIOFO A229 Plus Dash Cam Front and Rear, Dual STARVIS 2 Sensors, 2 Channel HDR, 1440P+1440P Voice Control Car Dash Camera, 5GHz Wi-Fi, Support 512GB Max, Voice Control, Ultra-Precise GPS - VIOFO 256GB Industrial Grade microSD Card, U3 A2 V30 High Speed Memory Card with Adapter, Support Ultra HD 4K Video Recording --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/389018170-hk4-acc-hardwire-cable-usb-c-hard-wire-cable-a329](https://www.desertcart.dk/products/389018170-hk4-acc-hardwire-cable-usb-c-hard-wire-cable-a329) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
