Cable Routing in Moving Gaps: Hinges, Sliders & Strain Relief

Most "mystery resets" are just bad cable routing. Build it once, build it right.

1) Hinge-Side Routing (Swing Doors)

• Use a flexible rubber loom between body and door; match OEM style when possible.
• Leave a service loop inside the door (10–15 cm) to prevent tug on connectors.
• Secure the harness every 15–20 cm; no free-floating wire whips.

2) Sliding Door Tracks

• Route above/beside the track with liquid-tight flex conduit and soft clamps.
• Keep hardware clear of the slide path; verify at full travel and with the van slightly twisted (ramps).

3) Anti-Chafe & Pass-Throughs

• Rubber grommets or bulkhead glands where metal edges exist.
• Braided sleeve over cable; heat-shrink at ends; label polarity and destination.

4) Connectors & Strain Relief

• Use keyed quick-disconnects (XT30/Micro-Fit style) near the escutcheon.
• Zip-tie anchors with adhesive + mechanical fastener; adhesive alone will fail in heat.

5) Test Like You Drive

• Open/close door 50× slowly and 10× quickly; watch the harness path each time.
• Road-test over bumps; re-inspect clamps and loom for witness marks.
