ConnectPRO CPH-TRAP16 Trapezoid 16 Pin to ISO Harness Adapter
ConnectPRO CPH-TRAP16 Trapezoid 16 Pin to ISO Harness Adapter
Vehicle-to-head-unit harness adapter converting a 16-pin trapezoid head unit connector to standard ISO connections, enabling clean plug-and-play wiring between compatible Alpine, Pioneer, and Mongoose 9-inch trapezoid head units and the vehicle's factory harness.
Product Overview
The ConnectPRO CPH-TRAP16 is a wiring harness adapter designed to bridge the 16-pin connector found on compatible trapezoid head units to the standard ISO connection format used by many vehicle factory harnesses. Trapezoid-format head units from Alpine, Pioneer, and Mongoose use a 16-pin proprietary connector that does not connect directly to ISO-standard vehicle harnesses without an adapter. The CPH-TRAP16 resolves this by providing the correct interface between the head unit's 16-pin output and the vehicle's ISO wiring, simplifying installation and eliminating the need to cut or splice wiring on either side.
Compatible with the Alpine INE-AW409S, INE-AX809, INE-AW409S-10, INE-AX809-10, Pioneer DMH-AP6650BT, and Mongoose Q9WCA, the CPH-TRAP16 is a practical companion accessory for any installation involving these popular aftermarket multimedia receivers. Always verify your vehicle's factory harness connector type against the ISO standard before purchasing.
Features & Benefits
16-Pin Trapezoid to ISO Conversion Converts the 16-pin proprietary connector on compatible trapezoid head units to the standard ISO connection format, enabling a clean and direct wiring connection to ISO-equipped vehicle harnesses without cutting or splicing.
Compatible with Leading Trapezoid Head Units Designed for use with the Alpine INE-AW409S, INE-AX809, INE-AW409S-10, and INE-AX809-10, Pioneer DMH-AP6650BT, and Mongoose Q9WCA — covering the most widely installed 9-inch trapezoid multimedia receivers in the Australian market.
Plug-and-Play Connection Provides a direct plug-in connection between the head unit and the vehicle harness with no wire cutting required on the head unit side, keeping the installation clean and reversible.
Simplifies Trapezoid Head Unit Installation Removes the wiring complexity associated with connecting trapezoid-format head units to ISO vehicle harnesses, reducing installation time and the risk of wiring errors.

Frequently Asked Questions
What does the CPH-TRAP16 connect?
The CPH-TRAP16 connects the 16-pin proprietary connector on compatible trapezoid head units to a standard ISO vehicle harness connection. This allows the head unit to be wired directly to the vehicle's factory harness via ISO connections without cutting or modifying the head unit's wiring loom.
Which head units is the CPH-TRAP16 compatible with?
The CPH-TRAP16 is compatible with the Alpine INE-AW409S, INE-AX809, INE-AW409S-10, and INE-AX809-10, the Pioneer DMH-AP6650BT, and the Mongoose Q9WCA. Confirm your head unit model before purchasing.
Does my vehicle need to have an ISO harness for this adapter to work?
Yes. The CPH-TRAP16 outputs a standard ISO connection, which must match the connector type on your vehicle's factory harness or a vehicle-specific ISO wiring harness adapter. If your vehicle does not use an ISO harness natively, a vehicle-specific ISO harness adapter will be required in addition to the CPH-TRAP16.
Do I still need a vehicle-specific wiring harness with this adapter?
In most cases, yes. The CPH-TRAP16 handles the head unit side of the wiring connection. A vehicle-specific wiring harness that connects to your car's factory plug on one side and ISO on the other is typically required to complete the installation. Consult a qualified car audio installer to confirm the correct harness combination for your specific vehicle and head unit.
Can I use the CPH-TRAP16 with other trapezoid head units not listed?
No. The CPH-TRAP16 is designed specifically for the 16-pin connector used by the listed Alpine, Pioneer, and Mongoose models. Other trapezoid head units may use different connectors or pin configurations and are not compatible with this adapter.
