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. Review: Sensing wire works great. - The old power supply failed. This on is much better, heavier gauge wire and coating. ## 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. The hardwire cable length is 13.1ft (4m). - DO NOT SUPPORT VIOFO A229 Duo, T130 , A119 MINI dash cam. This Device is the only Hardwire Device Compatible with the VIOFO A129 & A119 V3 Dash Camera. - The VIOFO Camera's Must be Updated to the Latest Firmware in Order to Enable Parking Mode and Use This Device. - Older Versions of the VIOFO Hardwire cables Such as The A119 Hardwire cable are NOT COMPATIBLE With The A129 or The A119 V3 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JQ1JYPJ | | Are Batteries Included | No | | Auto Part Orientation | Drivers Side | | Auto Part Position | Rear | | Best Sellers Rank | #10,665 in Electronics ( See Top 100 in Electronics ) #156 in Car On-Dash Mounted Cameras | | Brand | VIOFO | | Built-In Media | Hardwire Kit | | Color | Red | | Compatible Devices | Monitor | | Compatible with Vehicle Type | Car | | Connectivity Technology | Wired | | Control Method | Touch | | Customer Reviews | 4.4 4.4 out of 5 stars (2,733) | | Display Type | LCD | | Field Of View | 120 Degrees | | Frame Rate | 30 FPS | | Item Weight | 136 Grams | | Manufacturer | VIOFO | | Mfr Part Number | A129HW | | Model Name | A129HW | | Model Number | A129HW | | Mounting Type | Adhesive Mount | | Optical Sensor Technology | CMOS | | Other Special Features of the Product | Parking Monitor | | Real Angle of View | 120 Degrees | | Screen Size | 2.7 Inches | | UPC | 762931889344 | | Unit Count | 1.0 Count | | Video Capture Resolution | 2160p | ## Product Details - **Brand:** VIOFO - **Color:** Red - **Connectivity Technology:** Wired - **Field Of View:** 120 Degrees - **Included Components:** Hardwire Kit - **Model Name:** A129HW - **Mounting Type:** Adhesive Mount - **Special Feature:** Parking Monitor - **Vehicle Service Type:** Car - **Video Capture Resolution:** 2160p ## Images ![VIOFO HK3 Acc Hardwire Cable for A129, A129 Plus, A129 PRO, A129 IR, A119 V3, Enables Parking Mode, Low Voltage Protection (Fuse Tap Not Included) - Image 1](https://m.media-amazon.com/images/I/61VCJz5Pj7L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality product *by A***M on March 29, 2020* This is a great three wire hardwiring kit and is the third of three that I’ve installed.

This on is much better, heavier gauge wire and coating. ### ⭐⭐⭐⭐⭐ Quality materials and generous length *by E***I on October 24, 2024* The wires themselves feel very quality and not cheap at all. They give you so much length that I'd be surprised if anyone managed to run out with their install. Works as it should and that's all there really is to it. Easy enough to install at home with the help of some youtube videos (even for an idiot like me when it comes to wiring/electrical work). Highly recommend for any Viofo cam owners contemplating the purchase ## 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.is/products/95599963-viofo-hk3-acc-hardwire-cable-for-a129-a129-plus-a129](https://www.desertcart.is/products/95599963-viofo-hk3-acc-hardwire-cable-for-a129-a129-plus-a129) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-23*
