My Nav unit was stolen and wires cut in my 05 Tahoe LT with the Bose system.
I ordered new plugs but I could only find a diagram for the 24 pin plug not the 12 pin. I am looking for a either a picture of the 12 pin plug or a pin out wiring diagram. Can anyone help. I am about to lose my mind.

 

without specifics this is the only 12 pin connector I could find...

 

That's it. Thanks, Jeff. For future reference, where did you find this? I bought Chiltons manual and it wasn't in there.

One source is the Factory Service Manual available to order from Helm, Inc.

 

73shark pretty much said it, I have an electronic version of the factory service manual...
I know the factory manual seems like a lot of money (~150) but they are indispensable when you need accurate, exact to drawing info...

 

thanks, Jeff. The 12-way worked. Could I trouble you for the 24-way too. I am having a hard time finding one that calls out connections with y91. (luxury I gather) I have 16 wires which includes 2-bare. Can't find a diagram that matches.
Thanks again,
Steve
