Product Details
The Thermo King Harness WPAN 421358 is a dedicated wiring harness that connects WPAN communication modules to Thermo King controller assemblies. It delivers power, ground, and signal routing consistent with OEM harness design practices and uses industry-standard, sealed mating connectors where applicable. This harness follows Thermo King engineering conventions for secure mounting, protection from environmental exposure, and reliable data transmission in transport refrigeration installations.
Efficiency & Sustainability
By enabling reliable WPAN connectivity, this harness supports precise temperature control and remote diagnostics that contribute to fuel-efficient cooling and reduced operational waste. When paired with Thermo King telematics platforms (for example, Smart Reefer SR-4), WPAN-enabled workflows support improved route planning and load management consistent with CARB Evergreen goals and modern transport refrigeration best practices.
Installation & Maintenance Tips
Route harnesses away from excessive heat and moving parts and secure with OEM-grade clamps and protective sleeving. Inspect harness routing and connector seals during scheduled maintenance intervals and confirm secure mating to controller and WPAN module connectors to preserve signal integrity.
Real-World Applications
This harness serves refrigerated trailers, truck-mounted reefer units, and other transport refrigeration platforms that use WPAN-enabled telematics or HMI interfaces. Fleets leverage this harness to enable local wireless configuration, on-site diagnostics, and auxiliary connectivity that streamline operations across long-haul and regional routes.
Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
