Ok. Here I go. And please dont argue about donating specialty parts between different vehicles. I am looking for info on how the GCC system is wired into the car because I have plans to transplant the system into my Pontiac Feiro. I am somewhat aware the hvac controls will have to be mocked up, and the entire radio unit gets donated. My big question is how does it get wired into the car to get info for the display. Any help or ideas would be great. Wiring info, pics, any help. I really want to keep everything 80's so this is my reasoning.
