About the PAC LPHTY01 LocPro Advanced T-Harness
Upgrade your Toyota's radio
Upgrade your Toyota's radio
Adding an aftermarket amplifier will beef up the sound of any audio system, even when you can't replace the factory radio. PAC's LPHTY01 LocPro Advanced T-harness makes amplifier installation a lot easier by giving you access to the speaker-level output signals from your Toyota-built factory radio. You can use this T-harness to connect to an amplifier or signal processor with speaker-level inputs, or to a line output converter with an amp.
Provides signal for your system
PAC designed this vehicle-specific T-harness to work with their LPA LocPro Advanced line output converters, but it'll also work with almost any sound processor or line output converter, as well as most amplifiers with high-level inputs. The harness also supplies the connection wires for low-power constant 12 volts (fused for your protection), accessory power, ground, and remote turn-on leads for a system device like an active signal processor.
Note: The power and ground wires in this harness will only support a low-current accessory, like an active line output converter or digital signal processor, and should not be used to power an amplifier.
How it works
First, you unplug the radio and install the T-harness. Two T-harness plugs go into the radio, the others snap into the plugs you just took out. You're then left with the radio still completely connected to your vehicle, with the addition of a pigtail of wires to use for adding an amp.
It comes wired for adding a sub
The T-harness pigtail includes four speaker-level channels, eight wires, that you can use for the sub amp's inputs. The amplifier will have to get its power and ground connections separately. The factory radio will still run all the speakers.
For powering a system, you'll need to cut and splice some wires
You can use all four of the T-harness's speaker-level channels for your aftermarket system's inputs. PAC has made provisions in this harness for sending your aftermarket amplifier's outputs back through the factory wiring and onto the speakers. The appropriate wire bundle has clearly marked labels showing you which wires to cut and where, which wires you'll need to cap off, and which wires you'll need to connect to your aftermarket amplifier's outputs.

More details on the PAC LPHTY01 LocPro Advanced T-Harness
Overview: The LPHTY01 T-Harness is designed to simplify adding one of PAC's LOCPRO line output converters to your factory radio, but can also be used when adding select models of other line output converters, audio processors, and amplifiers with speaker level inputs. The harness keeps you from having to cut or modify your vehicle's original wiring, providing a direct connection at the back of the factory radio. (You will hardwire the harness to the LOC, audio processor, or amp you install.) Please enter your vehicle information to confirm compatibility.
Vehicle Compatibility: The LPHTY01 harness is compatible with factory radio systems without an outboard amplifier in select 1987 and newer Toyota, Scion, and Subaru vehicles, including (but not necessarily limited to):
