Chevy HHR Network - Stock radio low level input questions?

Ok, yes I have read the above how to on tapping into the subwoofer low level input wires to the factory amp. Problem is that some of the links for the wire diagrams are broken. I hate cutting up the factory wires if I can avoid it. I have added a Parrot bluetooth device to my radio so far and bought a special harness to adapt it to the radio. Since I have done that I now have wires I am willing to cut (I don't mind cutting into this harness because it can be replaced or removed) but I need the pinouts / color codes to the plug that directly connects into the back of the factory deck. This should be low level at this point till it reaches my factory amp. Plus I am upgrading everthing (not just the sub) so I need front left and right signals and the remote turn on. Any help out there? Thanks in advance.
