I am installing a double din AVH-4000NEX into my 2005 H2 SUT. I cant seem to find the 12V ON/OFF (ignition) wire in the factory harness. Listed in the diagram I have, I see a "AUD ENABLE SIG" (PPL) A3 and "RADIO ON SIG" (PNK) B3, however these route to the AMP. I have installed a new amp and speakers and ran new speaker wire and RCAs. I could run my own ignition wire but would like to see if anyone out there has dealt with and knows which is the wire I am looking for. Maybe I have the wrong diagram? Yon can see the wiring diagram I am using as https://www.facebook.com/groups/HummerLovin/ I put it on my Facebook group because it was to big to upload here.


Thank you,

Looks like you need to run the 12V ON/OFF (ignition) wire. I will post more info after I run it, were to tap-in etc...
