Industry Platform
Custom harnesses for ICE and EV programs — engine and powertrain, orange high-voltage and battery, ADAS and sensor, body and chassis. Up to 1000V DC, CAN-FD / LIN / automotive Ethernet, IP67/IP69K sealed, built to IATF 16949 and IPC/WHMA-A-620 Class 3 workmanship.
Application Context
An automotive harness is the nervous and power system of the vehicle, and it has to survive a brutal environment for the life of the car. Under-hood circuits see -40°C to +125°C, constant vibration, and splashes of oil, fuel and coolant; chassis and braking leads take road spray and grit; body and lighting branches need thin-wall FLR2X / FLRY wire to save weight. General-purpose hook-up wire and unsealed connectors fail in that world — so automotive harnesses use cross-linked TXL/GXL/SXL primary wire, abrasion- and fluid-resistant protection, and sealed connector systems from the start. Every build follows IATF 16949 process discipline and IPC/WHMA-A-620 Class 2/3 workmanship under our ISO 9001 quality system.
The wiring changes job at every system. Powertrain harnesses manage the engine, fuel injection and transmission; orange high-voltage cable assemblies carry traction power between the battery, inverter and motor with HVIL interlock continuity at up to 1000V DC; ADAS and sensor harnesses move radar, camera and ultrasonic data over CAN / CAN-FD networks and automotive Ethernet; and body, interior and chassis branches handle lighting, comfort, ABS and wheel-speed. We build all of these as custom, sealed, tested assemblies — including commercial EV truck harness families and waterproof IP67/IP69K constructions for the harshest chassis locations.
Applications
Sealed, vibration-rated harnesses for every system on ICE and EV platforms.
Under-hood engine, fuel-injection, ignition and transmission-control harnesses that survive heat, vibration and fluid exposure right next to the powertrain, built with cross-linked TXL/GXL/SXL primary wire and sealed connectors.
Orange shielded high-voltage cable assemblies for battery packs, inverters, traction motors and on-board chargers, with HVIL continuity and the spacing a 1000V DC architecture demands.
Precision harnesses for radar, camera, ultrasonic and LiDAR sensors plus the data backbone that links them — built for clean signal integrity on CAN-FD and automotive Ethernet links.
Body/interior, lighting, door, chassis and braking harnesses — including ABS and wheel-speed leads exposed to road spray and grit — sealed to IP67/IP69K and routed with clips for clean retention.
Sealed off-road and powertrain branches that need rugged DT/DTM terminations can be quoted through our Deutsch connector cable assembly service.
Engineering Challenges
Material selection and process controls for under-hood +125°C service, vibration fatigue and thermal cycling next to the powertrain.
Approved-brand review, sealed interface selection, and alternatives for cost and lead-time risk — validated to USCAR-2 / LV214.
Branch length, bend radius, protection and fixation planned so the harness installs cleanly and survives the vehicle life.
Continuity, Hi-Pot, HVIL, pull-force and final inspection records planned to the right quality level for the program.
Technical Capabilities
IATF 16949 and IPC/WHMA-A-620 manufacturing with sealed connector systems, validated for under-hood, chassis and 1000V DC EV service.
Manufacturing Process
Quality & Testing
Every automotive harness gets continuity, hi-pot and circuit-mapping verification, with sealed-connector and HVIL checks where the application calls for it — all documented for lot-level traceability before it ships.
Why WHP
Sealed, tested harnesses built to the standards OEMs and Tier 1 suppliers require.
Automotive harnesses manufactured to IATF 16949 process discipline and IPC/WHMA-A-620 Class 2/3 workmanship under our ISO 9001 quality system — built to the requirement, not a repurposed industrial process.
Orange shielded HV cable, HVIL interlock continuity, 360° shield grounding and 1000V DC spacing for battery, inverter and traction-motor assemblies — not just legacy 12/48V wiring.
Connector systems and terminations selected and crimped to USCAR-2 and LV214 connector-validation requirements, with sealed IP67/IP69K interfaces for under-hood and chassis exposure.
Every harness gets continuity, hi-pot and circuit-mapping verification, with sealed-connector and HVIL checks where the application calls for it, before it ships.
We hold ISO 9001 and IPC/WHMA-A-620 workmanship certification, and build to the automotive standards OEMs and Tier 1 suppliers require.
