Multi-port Classic Car Circuit Block Splitter

Original circuit designs in traditional classic and modified vintage cars are often outdated. Retrofitting accessories—such as ambient lighting, upgraded audio systems, or auxiliary lights—frequently leads to issues like disorganized wiring, chaotic connections, and unstable power supply. These problems not only compromise the vehicle's interior tidiness but also create safety hazards like circuit overloads and short circuits, significantly increasing the cost of future maintenance and upgrades.

To tackle these challenges, Yiqi independently developed the DB-47 Multi-port Classic Car Circuit Block Splitter. Designed around the core needs of vintage vehicle modification—specifically wiring organization, stable power distribution, and easy maintenance—the splitter optimizes port layout and overall structure. It enables centralized distribution of multiple power lines and standardizes wiring arrangements, comprehensively enhancing the safety and tidiness of the vehicle's electrical system.

Core Product Specifications

Key Features and Advantages

1. Compact, Integrated Design for Flexible Installation

The Multi-port Classic Car Circuit Block Splitter is compact and weighs only 117g, occupying minimal space. It can be flexibly installed in concealed locations—such as the dashboard or battery compartment—without altering the vehicle's original structure, making it a perfect fit for the limited space and fixed configurations typical of vintage models.

2. Durable Materials for Stable, Safe Power Supply

The core conductive components are made of high-strength zinc alloy, offering excellent conductivity and preventing issues like voltage fluctuations or circuit overloads during simultaneous multi-device operation. The flame-retardant PC outer casing is resistant to high temperatures, oxidation, dust, and corrosion, ensuring long-lasting performance even in the demanding conditions of a vehicle interior.

3. Standardized Wiring to Significantly Reduce Maintenance Costs

The scientifically organized multi-port layout resolves the issue of messy wiring common in traditional modifications, enabling independent power distribution across multiple circuits without mutual interference. Subsequent circuit maintenance, troubleshooting, and equipment upgrades are made easier, effectively reducing the difficulty and cost of after-sales support for classic car restoration projects.

4. Broad compatibility and support for customization

It adapts to a full voltage range of 12–48V and is compatible with the electrical systems of the vast majority of classic cars, RVs, and yachts on the market. Additionally, Yiqi offers services such as private labeling, port parameter adjustments, and bespoke solution customization, supporting various cooperation models including sample procurement, bulk ordering, and long-term strategic partnerships.

Real-world Application Case

1.Case Background

A professional European classic car restoration workshop undertook the full restoration of a 1980s American vintage sedan. The vehicle's original wiring was severely aged and disorganized. The owner wanted to install aftermarket audio systems, ambient lighting, auxiliary lights, and USB charging ports. Traditional single-line power supply methods posed serious safety risks, such as loose connections and overheating due to overloads.

2.Application Solution

The workshop used the Yiqi Multi-port Classic Car Circuit Block Splitter to optimize and upgrade the vehicle's electrical system. The unit was mounted in a concealed area beneath the dashboard; the main port connected to the vehicle battery, while individual output ports connected to the various aftermarket electrical components. Leveraging the product's fast-acting fuse characteristics, the system achieved independent power supply and overload protection for each circuit.

3.Application Results

Post-modification, the vehicle's wiring was neat and organized, completely eliminating safety hazards like short circuits and overloads. Power supply to all electrical components was stable, with no issues such as flickering lights or audio interference. After a year of real-world use, the circuit showed zero faults, and routine maintenance efficiency improved by over 60%. The workshop has now designated the Yiqi circuit splitter as a standard component for its classic car restoration and modification projects.
