This GM UNIVERSAL amplifier T-harness allows you to keep your factory radio (NON-BOSE) while adding in your new aftermarket amplifier(s) without the need to cut into or modify your OEM wiring. 

This is a universal harness, and provides a plug and play connection at the OEM radio, 8' or 17' cable, and RCA ends to connect into your chosen equipment (Line Converters, Digital Sound Processors, or directly to an Amplifier).  This kit also includes a loop-back harness with either wire ferrule terminals or spade terminals, from your multi-channel amplifier output, which will power your door & dash speakers without the need of running new wire to each speaker individually.

**This kit DOES NOT include a Line Out Converter OR Load Resistors.  This is a harness kit ONLY**

If you wish to have an option with a Line Out Converter installed, use this harness here:

 If you simply just need a 2 channel version to power an amp / sub only, use this harness here:

If you ONLY need the Radio T-harness option, use this harness here:

NOTES: 

**This kit DOES NOT include a Line Out Converter OR Load Resistors. This is a harness kit ONLY**

**For signal input, if your equipment (Line Out Converter / DSP / Amplifier) doesn't require RCA connections, you can cut off the RCA ends, strip the wiring, and directly connect your harness to your equipment's input**

NOTE: This harness is NOT for the BOSE factory audio systems.  If have the factory amplifier and are looking to bypass the factory amp, you will need the Pac Amp Pro / Harness system instead.
