Doors and handles
Wiring for handles, window systems, sensors, speakers, and door mechanisms.
Automotive applications
Automotive harnesses for doors, lighting, and controls
Build-to-spec assembly for handles, locks, headlights, shifters, side doors, liftgates, and power-closing systems.
Representative image. Final capability is confirmed against drawing, material, tolerance, and volume.
Capabilities
Repeatable processes for critical components
Automotive harnesses combine branches, connectors, grommets, clips, and protective materials that must be installed consistently. MJC structures each process around fixtures, visual instructions, inspection points, and approved criteria.
We do not assume specifications or component equivalents. Each program is quoted after validating drawings, materials, terminals, testing, and demand.
Lighting
Branches for front lamps, rear lamps, and signaling.
Controls
Connections for shifters, actuators, and related modules.
Power closures
Harnesses for locks, liftgates, and closing mechanisms.
Covered applications
The family may integrate vehicle-zone-specific configurations.
- Handles and internal door systems.
- Front and rear lighting.
- Shifters and shift controls.
- Side doors and window systems.
- Liftgates and rear doors.
- Power locks and closing systems.
Production control
Controls are defined with the customer and may include master samples, assembly fixtures, presence verification, connector inspection, labeling, and documented testing.
- First-piece release.
- Component and lot identification.
- Visual standards for routing, tapes, protection, and clips.
- Inspection records aligned to the control plan.
Frequently asked questions
Can MJC support launch programs?
Yes. We can evaluate introduction and ramp-up programs when controlled documentation and a validation plan are available.
Does MJC substitute components?
Any substitution must be formally evaluated and approved by the customer before production.
Can MJC integrate subassemblies?
We can evaluate related electrical or mechanical subassemblies as part of the harness process.
Process
From technical review to delivery
A clear workflow for integrating processes without losing visibility.
Review
We analyze drawings, materials, volume, acceptance criteria, and risk.
Proposal
We define scope, responsibilities, process route, and control points.
Validation
We release a sample or first piece before recurring production.
Production
We execute, inspect, report, and continuously improve the process.
