APH-TY01 Speaker Connection Harness

Speaker Connection Harness for Select Toyota Vehicles with Factory Amplifiers

Equipped with a 10-Pin and 12-Pin Connector

Introduction and Features

The APH-TY01 simplifies speaker wire connections when adding aftermarket amplifiers. Aftermarket amplifiers can be easily added with no need to cut or modify a vehicle's original wiring. Each pair of wires has been labeled with the corresponding speaker name.

Installation Notes

It is always best to use a tone generator (PAC part number TL-PTG2) to verify that the tables in this manual, and the labels on the wires, match the wiring in your specific vehicle. This is important as there are instances where different trim levels of the factory system may have the speaker outputs in different locations.
Not all applicable vehicles will come equipped with a corresponding speaker for all of the wires populated in our harness. It is important to understand which speakers are equipped in your vehicle.
If you are leaving any of the factory speakers connected to the factory amplifier, simply connect the speaker wires (color for color) between the male and female connectors. For example: If you want the rear speakers to be powered by the factory amplifier, simply connect the Green, Green / Black, Purple and Purple / Black wires from the male connector to the Green, Green / Black, Purple and Purple / Black wires from the female connector.
For vehicles that lose audio output when there is no load on the speaker outputs of the factory amplifier, PAC load resistors will be required (PAC Part Number LR335 or LR475).

Installation Steps

Locate the vehicle's factory amplifier and disconnect the 10-pin and 12-pin connectors.
Connect the APH-TY01 harness to the connectors that were disconnected in the previous step.
Connect the male connectors from the APH-TY01 to the amplifier.
Connect the longer loose wires from the APH-TY01 to your aftermarket amplifier outputs or passive crossovers according to the tables in this manual.
Insulate unused wires in the 10-pin and 12-pin connectors that plug into the factory amplifier side of the APH-TY01.
