Does anyone have a pdf. or something explaining what wires go to what on the back of the head-unit? I'm in complete disarray on what goes to what . Any information appreciated. 03 sedan non-bose. Thanks in advance!

 

Look over at www.infinitihelp.com. They have the complete factory service manual.

 

ah thank you, I was looking for this as well.

 

I tried the manual but it has no detail on what each wire represents.

 

its the AV PDF just look for the first pages of the pdf file you will see the Schematics but if you want more details such as how many volts each pin carry out look for "Terminals and Reference Value for Audio Unit for Base System" and you will see each pin on Harnesses M39,M40 remember Non-Bose = Base System.

 

yeah thanks I finally got it all wired and put togeather today. Nice 8 hour's in the cold and darkness trying to solder wires thanks for the help
