PAC LPHGM51 LocPro Advanced T-Harness for Select 2014-Up GM Vehicles

The PAC LPHGM51 LocPro Advanced T-Harness for Select 2014-Up GM Vehicles provides a clean connection to the factory radio's speaker-level outputs when adding an aftermarket amplifier, line output converter, or signal processor to a compatible vehicle without an outboard factory amplifier. It keeps the original radio connected and avoids cutting the factory radio wiring.

At a Glance

• Vehicle-specific T-harness for compatible non-amplified factory radio systems
• Provides four channels of speaker-level signal from the factory radio
• Provides speaker-return connections when the new amplifier will power the factory speaker wiring
• Includes low-current power, ground, accessory, and remote-turn-on connections where supported
• Works with PAC LocPro Advanced converters and many processors or amplifiers with speaker-level inputs
• Does not include a line output converter, signal processor, amplifier, or amplifier power kit

Exact Vehicle Compatibility

Find your vehicle below, then match the model year and factory-radio details in the same row. This harness is for the listed non-amplified factory systems; vehicles with a separate factory amplifier require a different integration solution. If the radio, connector, audio package, or equipment differs, contact MCOR before ordering.

Compatibility & What You Need

• Factory system: A supported factory radio without an outboard factory amplifier.
• Signal conversion: Add a line output converter when the amplifier or processor does not accept speaker-level inputs.
• Amplifier power: Run a properly fused amplifier power and ground kit directly for the amplifier; the small power and ground leads in this harness are only for a low-current converter or processor.
• Factory-radio load devices: Install the AudioControl AC-LGD model shown in the fitment table when specified so the factory radio continues to provide a usable audio signal.
• Extension option: {internal_link("LPHEXT17", "PAC LPHEXT17 17-foot extension")} is available when the processor or amplifier will be mounted away from the radio.
• Professional installation and system tuning are strongly recommended.
