Audio Systems: Line output converter, line output converter, pontiac sunfire

Question
I want to install subs in my 2002 Pontiac Sunfire. I have installed many stereos in the past but the GM wiring diagrams I have found do not match my car. I don't know what wires to connect the converter to and what wire is the P. Cont. for the amp. Can you help me with this?

Answer
YOU HAVE TO BE CAREFULL WITH THAT RADIO IF ITS IS THE LATE 2002 and rds radio that explains why you don't find the correct wires this radio trsmit data on the speaker cable any hi/low is going to give you serius problems like air bag light and wrong readings on the cluster or losing the chime noise from the drivers door speaker  you need the pac C2A GM24 here is the link
