9 Way 9-Relay Pre-Wired Fuse Box
Product Overview
The 9 Way 9-Relay Pre-Wired Fuse Box is a high-capacity automotive power distribution and circuit control solution designed for multi-accessory DC electrical systems.
It integrates 9 ATC/ATO blade fuse positions and 9 automotive relay positions into one enclosure, allowing each circuit to be independently protected and relay-controlled.
The pre-wired harness reduces terminal crimping, relay socket assembly, and complicated manual wiring, helping installers save installation time and create a cleaner, more organized electrical system.
This fuse relay box is suitable for auxiliary lighting, driving lights, work lights, horns, cooling fans, fuel pumps, auxiliary pumps, audio equipment, and other automotive electrical accessories.
Relay specifications can be selected according to customer requirements. Available relay configurations include 12V and 24V systems with approximately 30A to 60A relay ratings, depending on relay model, wiring specification, load characteristics, and project requirements.
In addition to complete pre-wired assemblies, FUZTRAX can also supply housing, terminals, relays, fuses, and related components separately for OEM, ODM, wiring harness manufacturers, vehicle builders, and aftermarket electrical suppliers.
Key Features
9 Fuse Positions + 9 Relay Positions
The integrated design combines nine ATC/ATO blade fuse positions and nine automotive relay positions in one housing.
This configuration allows each protected circuit to be paired with an independent relay-controlled output.
It is particularly suitable for complex vehicle electrical systems where multiple accessories require separate switching and fuse protection.
Pre-Wired for Faster Installation
The pre-installed wiring harness helps reduce repetitive terminal crimping, relay socket wiring, and manual assembly.
Color-coded wiring makes circuit identification easier and helps reduce wiring errors during installation.
For OEM and ODM projects, wire gauge, wire length, wire color, terminal configuration, and wiring layout can be customized according to customer requirements.
9 Independent Relay-Controlled Circuits
Nine relay positions allow multiple electrical accessories to be controlled independently.
Typical applications include:
The 9-relay configuration provides greater control flexibility for vehicles and equipment with multiple auxiliary electrical systems.
12V / 24V Relay Options
Relay configurations are available for common automotive and equipment electrical systems.
Available voltage options include:
Available relay ratings may include:
Final relay selection should be based on:
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 individual circuits according to the actual operating current of the connected equipment.
This makes fuse selection, replacement, and maintenance convenient for automotive aftermarket, vehicle modification, and custom wiring applications.
Centralized Power Distribution
Instead of installing multiple standalone relays, inline fuse holders, and scattered wiring throughout the vehicle, this fuse relay box integrates nine fused and relay-controlled circuits into one centralized location.
The compact layout helps reduce wiring clutter, simplify circuit management, and create a cleaner, more professional electrical installation.
Protective Top Cover
The fitted top 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 according to customer requirements.
Complete Pre-Wired Assembly
Includes housing, terminals, relays, fuses, and pre-installed wiring.
Suitable for customers who require a ready-to-install electrical assembly.
Unwired Fuse Relay Box
The product can also be supplied without pre-installed wiring.
This option is suitable for professional installers, wiring harness manufacturers, OEM customers, and vehicle builders who prefer to create their own wiring configuration.
Housing + Terminal Kit
Housing and terminals can be supplied separately as a semi-finished component kit.
Relay and Component Supply
Relays, terminals, fuses, and related components can also be supplied separately according to customer order requirements.

Why Choose the 9 Way 9-Relay Configuration?
The 9 Way 9-Relay configuration is designed for electrical systems that require a large number of independently controlled accessories.
Each of the nine circuits can be protected by an individual fuse and controlled through a dedicated relay, making the system easier to organize and manage.
Compared with installing multiple separate relays and fuse holders, the integrated design helps reduce wiring complexity and keeps major protection and switching components in one centralized enclosure.
This configuration is particularly suitable for off-road vehicles, trucks, SUVs, RVs, special-purpose vehicles, custom builds, and OEM electrical systems with multiple auxiliary accessories.
OEM & ODM Customization
FUZTRAX provides OEM and ODM manufacturing services for automotive fuse boxes, relay boxes, wiring harnesses, terminals, and related electrical assemblies.
Customization options include:
Customers can order complete pre-wired assemblies or purchase housings, terminals, relays, fuses, and other components separately 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:
-
Wire cross-sectional area
-
Fuse rating
-
Relay contact rating
-
Terminal capacity
-
Connector capacity
-
Operating current
-
Starting or inrush current
-
Ambient temperature
-
Installation method
-
Electrical load characteristics
Always select the appropriate relay, fuse, wire gauge, terminals, and connectors according to the actual electrical requirements of the connected equipment.
For high-current, motor-driven, or specialized electrical applications, confirm the required operating current and system specifications before ordering.
