2014-2018 Chevy T- Harness for Audio Upgrade (Non-Bose)

[Chino1777]

This T-Harness will work if your going to add a 4 Channel amp. 

 

The Metra 71-2107 Reverse Wiring Green Harness will provide the output of the headunit to the amplifier. Then connect from the amp to the Metra 70-2057 Amp Bypass Green Harness which this create the T- Harness.

Which then it connects to the Factory Green Harness to provide the power signal from the amp to your aftermarket speakers. For power and ground connect the yellow (pin 8) and black (pin 16) wires from the Metra 71-2107 to the Yellow/Black (Pin 1) and Yellow/Black (Pin 9) of the Metra 70-2057.

I haven't able to hook it up since I had to work out of town. I'll have more pictures once I hook it up.
