APH-TY04
Toyota and Lexus Vehicles with Factory Ampliers
Equipped with a 10-Pin and 12-Pin Connector
Introduction and Features
The APH-TY04 simplies speaker wire connections when adding aftermarket ampliers. Aftermarket ampliers 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
1. 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 specic vehicle. This is important as there are instances where different trim levels of
the factory system may have the speaker outputs in different locations.
2. Any factory amplier connectors other than the 10-pin and 12-pin connectors used by the APH-TY04, must remain
connected to the factory amplier when using a PAC AmpPRO Interface. The PAC AmpPRO Interface will not operate
properly without them connected.
3. 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.
4. If you are leaving any of the factory speakers connected to the factory amplier, simply connect the speaker wires (color for
color) between the male and female connectors, for the speakers that will be powered by the factory amplier. For example:
If you want the rear speakers to be powered by the factory amplier, 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.
5. For vehicles that lose audio output when there is no load on the speaker outputs of the factory amplier, PAC load resistors
will be required (PAC Part Number LR335 or LR475).
Installation Steps
1. Locate the vehicle’s factory amplier and disconnect the 10-pin and 12-pin connectors.
2. Connect the APH-TY04 harnesses to the connectors that were disconnected in the previous step.
3. Connect the male connectors from the APH-TY04 to the amplier.
4. Connect the longer loose wires from the APH-TY04, to your aftermarket amplier outputs or passive crossovers, according
to the tables in this manual.
5. Insulate unused wires in the 10-pin and 12-pin connectors that plug into the factory amplier side of the APH-TY04.
