Need +12 volt constant wire color

Hey all, I'm installing a Peripheral iPod2car interface, and it requires me to splice into the +12 constant wire; and ground.. Does anybody know what color these wires are?
I have a 2005 silverado LT with the Bose 6 speaker system.. Thanks!

I have a schematic of your radio. Let me know if you can't find the orange wire. I'm sure there are other sources of 12+.

Ground = BLK/WHT 1851 (you should be able to attach to the chassis, just find a screw or bolt attached to your metal frame work under the dash some where)

12+ = Orange 340 (comes from the radio 15A fuse, in the fuse box, located underhood)


You could go straight to the fuse box to "Aux. Pwr 2 Fuse 20A" shows it not being used.

I'll try that, thank you very much!

This one is located in the fuse box inside the cab. Just inside the drivers side door, I believe. You may have to install the 20A fuse. I don't know if it's there. If you look up underneath the dash, hopefully there is a pin or blade labeled Aux 2 that you can connect to without having to splice any wires.

Looks like the back side is labeled "A10" and "G" there are two 12+ off of Aux2.


Any time. I have the GM service manual 1998-2005 that others here have.
Now, if I could only trade a schematic or info for a VIN lookup.

Cool thanks a billion, got er all hoooked up and it works great.. Found the orange wire behind the deck and spliced into it. The fuse box did have a 20A Aux 2 port, and a fuse installed, but I couldn't figure out where it is in the back there was no labeling. Just had to use a standard blue wire splicer it was easy as pie.

Thanks again! =D

Your Welcome, glad to here everythings working for you.
