9 Way Pre-Wired Fuse Relay Box
Product Overview
The 9 Way Pre-Wired Fuse Relay Box is a compact and flexible automotive power distribution solution designed for auxiliary DC electrical systems.
It combines 9 ATC/ATO blade fuse positions and 3 automotive relay positions in one enclosure, providing centralized circuit protection and relay control for multiple electrical accessories.
The pre-wired harness reduces terminal crimping, relay socket assembly, and complicated manual wiring, helping installers build cleaner and more organized vehicle electrical systems.
This fuse relay box is suitable for auxiliary lighting, fog lights, work lights, horns, cooling fans, fuel pumps, auxiliary pumps, audio equipment, and other automotive electrical accessories.
Standard configurations can be supplied with automotive relays according to customer requirements. Relay voltage and current ratings can be customized from approximately 12V to 72V and 30A to 60A, depending on the relay model, wiring specification, and application requirements.
In addition to complete pre-wired assemblies, FUZTRAX can also supply housing, terminals, relays, fuses, and related components separately for customers who prefer to build their own wiring system.
Key Features
9 Fuse Positions + 3 Relay Positions
The integrated design combines nine ATC/ATO blade fuse positions and three automotive relay positions in one compact housing.
The nine fuse positions provide circuit protection for multiple accessories, while the three relay positions allow selected higher-current electrical loads to be controlled through relay switching.
This configuration is suitable for projects that require several protected circuits but only a limited number of relay-controlled outputs.
Pre-Wired for Easier Installation
The pre-installed wiring harness helps reduce repetitive crimping, terminal assembly, and relay socket wiring.
This makes installation more efficient and helps reduce wiring errors during automotive modification, aftermarket installation, and custom equipment assembly.
Color-coded wiring can also be configured according to customer requirements for easier circuit identification.
Flexible 9-Circuit Power Distribution
The 9-way fuse layout provides multiple protected circuits in one centralized location.
It is suitable for distributing power to several auxiliary accessories while keeping fuses, relays, and wiring organized inside one enclosure.
The centralized design can help reduce loose inline fuse holders, scattered relays, and unnecessary wiring around the battery or electrical compartment.
3 Independent Relay Positions
Three relay positions provide independent switching control for selected electrical accessories.
Typical relay-controlled applications may include:
The remaining fuse positions can be used for other protected circuits according to the customer's wiring design.
Custom Relay Configurations
Relay specifications can be selected according to system voltage, load current, and customer application requirements.
Available configurations may include:
Final relay selection depends on the relay model, system voltage, wire gauge, terminals, connectors, load characteristics, and operating environment.
ATC / ATO Blade Fuse Compatible
The fuse block is compatible with commonly used ATC/ATO automotive blade fuses.
Different fuse ratings can be selected for different circuits according to actual accessory current requirements.
This makes fuse replacement and maintenance convenient for automotive aftermarket, vehicle modification, and custom electrical applications.
Protective Cover Design
The fitted upper cover helps protect the fuses, relays, and terminals from dust, dirt, debris, and accidental contact.
This product is not waterproof.
It should be installed in a dry or protected location and should not be directly exposed to rain, water spray, high-pressure water, or immersion.
Multiple Supply Options
FUZTRAX can supply this product in different configurations depending on customer requirements.
Complete Pre-Wired Assembly
A complete fuse relay box with housing, terminals, relays, fuses, and pre-installed wiring.
Suitable for customers who require a ready-to-install electrical assembly.
Unwired Fuse Relay Box
The fuse relay box can also be supplied without pre-installed wiring for customers who want to create their own wiring layout.
This option is suitable for professional installers, wiring harness manufacturers, and custom vehicle builders.
Housing and Terminal Kit
Housing and terminals can be supplied as a component kit for customers who prefer to assemble the product locally.
Relay and Component Options
Relays, terminals, fuses, and other related components can also be supplied according to the customer's order configuration.

Why Choose the 9 Way Fuse Relay Box?
The 9 Way Fuse Relay Box provides a practical balance between circuit capacity, relay control, and installation space.
For vehicle electrical projects that require multiple protected circuits but do not need a relay on every circuit, the 9-fuse and 3-relay configuration provides a flexible and cost-effective solution.
It helps centralize electrical protection and switching components, reduce scattered wiring, and create a cleaner electrical installation.
The product can be supplied as a complete pre-wired assembly or as individual components, making it suitable for both end-product installation and OEM manufacturing projects.
OEM & ODM Customization
FUZTRAX provides OEM and ODM manufacturing services for automotive fuse boxes, relay boxes, terminals, wiring harnesses, and related electrical assemblies.
Customization options include:
Customers can order complete pre-wired assemblies or select individual components according to their own production and assembly requirements.
Important Electrical Notice
The current rating printed on a relay represents the relay contact specification and does not automatically represent the safe continuous current capacity of the complete fuse relay box or wiring harness.
Actual allowable circuit current depends on several factors, including:
Always select the appropriate fuse, wire gauge, terminals, connectors, and relay specification according to the actual operating current of the connected equipment.
For high-current, high-voltage, or specialized electrical applications, confirm the required electrical specifications before ordering.
