The wiring harness that is needed for a 01+ is the MET 801771. This is all one plug, but to do the same thing I mentioned before just cut the white, white/black, green, green/black, grey, grey/black, purple, and purple/black wires and run those to the RCAs. Tape off the end going into the aftermarket HU, and the other end is the one to run to the RCA preouts. Same concept, very simple to do. Now, does anyone else need their car washed with my "dirty rag"?
