I intend to install a GT3 console delete, and my 99 c2 has PCM from factory. No bose, no amp, no door speakers. I'm having some trouble finding a wiring harness adaptor and I'm hoping someone here might know of a solution. I have 5 total wiring connectors - at least 1 is for the nav drive, and the other for the CD changer, both of which will be removed. It seems the PCM has a different set of connectors and no one makes an adaptor?
I hope you can follow the wiring schematics below because they are your road maps to getting it wired up correctly. At the essence of the PCM are the two 26 pin connectors (2nd picture) in your hand are the core of what makes the PCM the PCM. They mostly handle navigation IO between the headunit and Navigation module as well as the OEM telephone. Therefore, if you're installing a basic aftermarket radio, then you don't need those two connectors. If you plan to decommission the CD changer, then you don't need the smaller GREEN and BLUE ISO PLUGS C2 and C3. To make this work, you need to concentrate on wiring the 8-pin ISO PLUGS A and B (BROWN AND BLACK) as shown in the first picture. Let me know if you have questions.
You should order this wiring harness. You won't need the RCA pre-amp harness since you don't have a separate amplifier, but good to have for future installs. https://www.crutchfield.com/p_120701...s.html?tp=2977
