⚠️ Compatibility Notice
This kit is designed to fit all Holden Colorado and Holden Trailblazer models (2017–2022). It includes two harness configurations — a Low Profile and a High Profile harness — to ensure compatibility across every trim level, from entry-grade work models to top-tier variants equipped with the MyLink infotainment system.

✅ Included Harnesses:

• Low Profile Harness:
  Commonly used in Holden Colorado LS, LSX, and LT variants, as well as the Holden Trailblazer LT. These models generally feature the standard 6-speaker audio system and non-MyLink configuration. When using this harness, the factory reverse camera will be retained. However, if your vehicle is fitted with a 360° camera system and requires the Low Profile harness, the 360° camera will not be retained.

• High Profile Harness:
  Most frequently used in Holden Colorado LTZ and Z71 models, along with the Holden Trailblazer LTZ and Z71 variants. These trims typically include the factory MyLink infotainment system, amplified premium audio, and, in some cases, the 360° camera system. If this harness connects to your vehicle, both the factory reverse camera and 360° camera (if equipped) will be retained.

🚫 Not Compatible With:

• Holden Colorado 7 (2012–2016) — earlier generation model with different dash design and wiring architecture.

• Holden Colorado or Trailblazer vehicles with aftermarket amplifier systems or non-standard rewired audio setups.

• Vehicles with factory navigation units differing from the MyLink system (common in export or fleet variants).

The correct harness depends on your vehicle’s internal wiring specification rather than just its exterior trim. Both harnesses are included to ensure correct installation across all supported configurations.

📷 To confirm compatibility, we recommend filling out our fitment form before placing your order.
