Technical Notes & What to Check Before Buying

Identify your DS3’s model year & specific version (pre-/post facelift, Crossback / E-Tense). Equipment and available wiring vary. :contentReference[oaicite:16]{index=16}
Check whether your vehicle has LED rear / brake lights – this requires LED-compatible wiring to avoid warning signals. :contentReference[oaicite:17]{index=17}
Verify whether the vehicle already has a tow socket or wiring harness – if yes, installation is simpler and faster. :contentReference[oaicite:18]{index=18}
Ensure cable routing is protected; connectors are shielded from moisture, heat, vibration. It improves longevity and avoids faults.
After fitting: test all lighting circuits: tail lights, indicators, brake lights; in 13-pin cases test reverse light, trailer power supply. Also check that any warning beacons or sensor alerts behave correctly.

How to Order the Right Wiring Kit

Determine exact model year & trim of your DS3 (Crossback / E-Tense etc.).
Choose wiring kit type: 7-pin for basic lighting, 13-pin for full features.
Select a kit, ensuring all required accessory options (LED-support, permanent power, etc.) are included.
Order, then install according to manual; if coding needed, plan workshop visit.
