This on is much better, heavier gauge wire and coating. Review: Quality product - This is a great three wire hardwiring kit and is the third of three that I’ve installed. The first was the Plozoe which was a two wire power supply. If only one power and a ground are needed it’s a great product with the best value as it includes 4 sizes of fuse taps that by themselves usually cost $7 a piece. It doesn’t have an selectable battery low charge feature. The second was the Power Magic Pro: what a piece of over-priced garbage. First off, it didn’t work out of the box which many have reported. You’re forced to retain the cigarette-like plug to adapt it to the dash cam, which makes it the most antiquated and inflexible of the hardwire kits. Warranty is voided if you remove the plug for more streamlined, less bulky terminals. The fork terminal for the ground is tiny; most grounding points that you’ll find will be M6 (10mm socket) or 1/4” bolts, so you either not find a suitable connection or have to source a larger M6 terminal to replace it with. The Viofo three wire affords you a battery power wire for parking mode and an ACC wire to wake up the camera when you start the car. The circuit board allows for multiple battery low charge protection limits and has nonproprietary USB connections. Hopefully this will become the new standard for dash cam hardwire kits. You must source your own fuse taps or splice into the vehicle power supplies which most pros suggest. The Viofo A129 Pro Duo with this power supply has been the best combo for the price, ease of use and performance. The small screen makes setup and monitoring current operation convenient and takes up a very small piece of windshield real estate. The Vantrue failed mostly because it would never wake up from parking mode (a three wire system would alleviate this problem). The Black Vue is very cheaply made for the cost. It has some nice features that make it an enticing option, but it’s in need of some serious updates and material upgrades to justify cost. The camera plastic is very cheap and the front camera jiggles around in the base. It also lacks a screen interface to quickly assess mode and operation. Save your money. ## Features - Note: The fuse tap not included. The installation of the harewire cable requires the connection of the circuit fuse taps. lf you need to buy the circuit fuse taps, please check the ASIN B08SJZJCV5. - This VIOFO Hardwire Cable Enables Parking Mode on the VIOFO A129, A129 PLUS, A129 PRO & A119-V3 Dash Camera.

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 ### ⭐⭐⭐⭐⭐ Sensing wire works great. *by W***E on March 2, 2026* The old power supply failed.

At the moment she's not driving much at all, her car sits for a week or so at a time, after the install I set the kits volt meter to 12.2V and in about a week after I last drove it I came home in my car and noticed it wasn't recording and the record light wasn't even blinking. I figured the kit must have shut down the parking mode to save the battery. When I got her keys to see if that was the case, sure enough the car started just fine and once running for a few seconds the camera came to life and started recording. Once she starts driving regularly again I'm confident that the kit will make sure her battery does die on her, specially with winter upon us. ## Frequently Bought Together - VIOFO HK3 Acc Hardwire Kit for A129, A129 Plus, A129 PRO, A129 IR, A119V3, Enables Parking Mode, Low Voltage Protection - VIOFO Dash Cam A119 V3 2K 2560x1440P Quad HD+ 60FPS Front Car Dash Camera, 5MP STARVIS Sensor, 140-Degree Wide Angle, GPS Included, Buffered Parking Mode, True HDR, Motion Detection, Time Lapse - VIOFO Circular Polarizing Lens CPL Filter for Use with A119MINI2, A129 Duo, A129 Plus Duo, A129 Pro Duo, A129 IR, A119 V3, A119 --- ## 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.tw/products/95599963-viofo-hk3-acc-hardwire-cable-for-a119-v3-a129-plus](https://www.desertcart.tw/products/95599963-viofo-hk3-acc-hardwire-cable-for-a119-v3-a129-plus) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-08*
