Trying to install a pioneer system in place of the original

Customer Question

Trying to install a pioneer system in place of the original Chevy system. I want to try to use the microphone in the headliner with the new system. Was looking to patch in somewhere if possible. Same question goes for the USB and audio input cconnections that are in the center console.

I am sorry that you have not been helped yet. I just came online and saw your question.

Ok, are you looking for where the wires run to physically connect to them by hardwiring in, or do you need the wire colors for them at the back of the factory audio unit harness connectors?

In either case, I will need the vin number to pull the schematics and if you have the audio model number as well

I assumed I could patch into one of the harnesses so yes, which harness and which color wire(s). VIN is 1GCRCPEH0EZ354559 and original unit is model 111000-55310101, GM P\N: 13592804

USB is red/violet for positive and black for ground

Microphone is black/brown for low reference and dark blue for signal

dont have a routing for them, sorry. I can opt out and see if anyone else does
