i have the avic f90BT. i know my installer was able to find everything using just the factory connectors. he didnt have to run any seperate wires anywhere.....so it all should be there.
here is alink where you can see all the factory connectors and pinouts. this may help identify what you are looking for.
i assume you are using the PAC or maybe the metra harness and can bus interfaces?
also, does your Jeep have the BA system, speakers and amp to start with?
