- Relay control Relays and control modules for auxiliary systems
- Harness project RFQ Connectors, terminals and sub-assemblies to your drawing
Typical Commercial & Special Vehicle Applications
How body builders, fleet upfitters and vehicle project teams use DAIERTEK components. Final model choice should follow the real circuit, load, environment and acceptance requirements.
Warning & Work Lighting Circuits
Switching, relays and fuse protection for beacons, strobes, scene lights and rear work lights on municipal, utility and roadside service vehicles.
Auxiliary Control Systems
Dash switches and relay control for PTO, auxiliary heaters, fans and other added functions, keeping heavy current away from the cab panel.
Harness Sub-Assemblies
Connectors, terminals, fuse holders and wiring components for harness sub-assemblies built to the project drawing and connector interface.

View MoreHow to Prepare a Vehicle Electrical Project
Share the circuit and load information first, then define the interfaces and agree the sample and approval plan.
01 / CIRCUIT & LOADS
Share the Circuit Diagram and Load List
Provide the circuit diagram, system voltage (12V or 24V), each load with steady and startup current, and the duty cycle. Existing part numbers, photos or drawings help identify the right components faster.
02 / INTERFACE
Define Protection, Switching and Connector Interface
Confirm fuse or breaker ratings for each circuit, which loads need relay control, and the connector types, terminals and wire gauges at each interface. Note the mounting location and environmental exposure.
03 / APPROVAL & VOLUME
Agree Samples, Acceptance and Volume
Align on sample quantity, test or acceptance requirements, labeling and packing, and the expected annual volume. This lets quotation, MOQ and lead time be planned for the project.
Commercial & Special Vehicles FAQ
A circuit diagram or harness drawing, component list, system voltage, load currents, connector and terminal requirements, and the estimated quantity. Photos or part numbers of existing components are helpful for replacement or matching projects.
Send the drawing, part number, photos and key dimensions of the existing component. Our team reviews the electrical rating, mounting interface and terminals, then confirms whether a suitable equivalent or custom option is feasible.
After the specification is agreed, samples can be arranged for fit and function checks. Acceptance criteria, sample quantity and timing are confirmed during quotation, and mass production follows your approval.
Components for one vehicle or one system can be discussed as a kit, with labeling and packing arranged for your assembly line or service team. Share the kit contents and quantity for a combined quotation.
Many commercial vehicles run on 24V. Check the voltage rating of each component, including relay coil voltage and indicator lamp voltage, and state the system voltage clearly in your enquiry.
