CANBUS Decoder Harnesses for Lighting Retrofits

Per-vehicle load simulation and sealed engine-bay leads — ending dashboard bulb-out warnings for an installer channel.

HID 9005 CANBUS decoder cable with sealed connectors
  • Client: installation channel (name withheld by agreement)
  • Division: Wire Harness
  • Products supplied: CANBUS decoder harnesses, sealed leads
  • Scope: load simulation per vehicle family, sealed terminations
  • Gate: written sample approval before mass production
The Brief

After the Upgrade, the Dashboard Complained

An installer channel fought dashboard bulb-out warnings after HID upgrades. The vehicles' CAN systems read the new lamps as failed bulbs, and the retrofit had to work across a list of vehicle families rather than one model.

What We Built

Match the Load the Car Expects

Load simulation

Decoder load matched per vehicle family, so the CAN system reads the lamp as present.

Sealed leads

Sealed terminations for engine-bay positions — splash and condensation, not just dry cabin.

One part number per family

The vehicle list mapped to a finite set of harness part numbers.

Sample approval first

Each family validated on samples before the batch run.

Outcome

Warning-Free Retrofits, Repeatable Builds

On the vehicle

  • Warning-free retrofits across the vehicle list.
  • One harness part number per family instead of cut-and-pray wiring.

In the channel

  • Installer-safe kits: keyed, sealed and labeled.
  • Repeat orders run against the approved sample.
A note on confidentiality: client identities stay private unless a client chooses to be named. When you ask about a program similar to yours, we can usually describe it in more detail on a call.
