Serviceability in Tight Tiny-House Interiors

If it takes more than five minutes to service, you over-engineered the wrong part.

1) Quick-Disconnect Inside the Door

• XT30/Micro-Fit style, keyed, labeled on both sides (+12V/GND or 5V/GND).
• Service loop: 10–15 cm extra cable with strain relief.

2) One-Tool Panels

• Unify fasteners (e.g., 2.5 mm hex everywhere).
• Keep a spare screw taped inside the cavity.

3) Ferrules & Termination Discipline

• Ferrules on all screw terminals; no frayed strands.
• Heat-shrink over splices; no exposed copper.

4) Documentation That Lives With the Door

• 3×5 card: wiring path, fuse rating, connector type, last service date.
• QR code to your local copy of install notes (works offline).

5) Post-Service Test

• 10 lock/unlock cycles. Listen for new noises.
• Torque-mark screw heads for visual drift checks.
