Overview
Modern climate systems combine multi-zone blower motors, actuator doors, and cabin sensors, all needing compact wiring that survives dash-panel heat cycling and years of daily use.
Design & Construction
Compact, Heat-Tolerant Bundling
Space-saving flat and round bundle constructions route through tight dash and HVAC housing cavities while tolerating sustained heat from blower motors and defrost circuits.
Actuator & Sensor Connector Matching
Connectors are matched to blend-door actuators, temperature sensors, and blower control modules, with keyed housings that prevent mis-mating during dash assembly.
Manufacturing Process
Built under IATF 16949 process controls with continuity and thermal-cycle testing on every harness, supporting climate control module suppliers across high-mix vehicle platforms.
Typical Applications
- Blower motor and resistor wiring
- Blend door actuator cabling
- Cabin temperature sensor harnesses
- HVAC control panel interconnects
- Defrost and vent control wiring
Common installations include Blower motor and resistor wiring, Blend door actuator cabling, and Cabin temperature sensor harnesses, where vibration resistance and long-term durability under continuous thermal cycling are the primary design drivers. The same base design can also be adapted for HVAC control panel interconnects and Defrost and vent control wiring with minor changes to connector type or cable length.
