CAC HISOPN3 16-Pin ISO Harness Compatible with Pioneer Aftermarket Head Units

CAC HISOPN3 16-Pin ISO Harness Compatible with Pioneer Aftermarket Head Units

Secondary ISO wiring harness for Pioneer aftermarket head units, converting the 16-pin Pioneer head unit connector to a standard double ISO connector for plug-and-play integration with vehicle-specific primary harnesses, with reverse camera trigger wire and locking clips for a secure, reliable connection.

Product Overview

The CAC HISOPN3 is a secondary ISO harness designed specifically for Pioneer aftermarket head units, providing the secondary wiring connection required to integrate the Pioneer 16-pin head unit connector into a standard double ISO system. By converting the Pioneer plug to a standard double ISO connector, the HISOPN3 enables the head unit to connect cleanly with vehicle-specific primary harnesses without cutting or modifying factory wiring.

The HISOPN3 includes a reverse camera trigger wire for activating reverse camera display on compatible Pioneer head units, and locking clips on both the ISO and head unit connectors provide a reliable, durable connection that resists vibration and accidental disconnection during installation and operation.

Note: The HISOPN3 is a secondary harness only and must be paired with a vehicle-specific primary harness to complete installation. For some vehicle and head unit combinations, minor harness modification may be required to complete the installation. Contact F.A.E. for guidance on your specific vehicle and head unit combination before ordering.

Frequently Asked Questions

Q: What is the difference between a secondary harness and a primary harness?

A: A primary harness connects the vehicle's factory wiring loom to a standard ISO connector. A secondary harness — like the HISOPN3 — connects the aftermarket head unit's proprietary plug (in this case Pioneer's 16-pin connector) to the other side of the ISO system. Both are required for a complete plug-and-play installation. The HISOPN3 handles the head unit side; a vehicle-specific primary harness handles the vehicle side.

Q: Do I need any other components to complete the installation with the HISOPN3?

A: Yes. The HISOPN3 is a secondary harness only and must be paired with a vehicle-specific primary harness matching your vehicle make, model, and year to complete the full electrical connection. Depending on your vehicle, a vehicle-specific fascia kit may also be required for a clean dashboard fit. Contact F.A.E. with your vehicle and head unit details for a complete parts list.

Q: Is the HISOPN3 compatible with all Pioneer head units?

A: The HISOPN3 is designed for Pioneer aftermarket head units using the 16-pin connector configuration. Not all Pioneer head units use the same connector type — if you are unsure whether your specific Pioneer model uses a 16-pin connector, check the rear connector panel of the head unit or contact F.A.E. for confirmation before purchasing.

Q: What does the reverse camera trigger wire do?

A: The reverse camera trigger wire sends a signal to the Pioneer head unit when reverse gear is engaged, instructing the head unit to switch the display to the connected reverse camera feed. This wire must be connected to the vehicle's reverse light circuit during installation for the reverse camera function to operate correctly.

Q: Will I need to modify the HISOPN3 for my installation?

A: For most standard installations, the HISOPN3 connects plug-and-play without modification. However, for some vehicle and head unit combinations, minor harness modification may be required to complete the installation. Contact F.A.E. with your specific vehicle and head unit details before ordering if you are unsure.
