Sierra

I'm having trouble installing a Alpine CDA-117 deck into a 2007 GMC Sierra "Classic style". I have the required wiring harness, and radio antenna. I attached all the wires as per each color, plugged it together, and plugged in the radio antenna. I can't get any power on the alpine unit. I'm not sure if having a BOSE factory system in my truck is causing any issues. Do anyone have any idea what I'm missing here? Thank you

What is the make and model number of the wiring harness?

alot of the time the problem with these gm's are they don't have an acc wire, so you can get this module and it will give you the acc wire, or you can run the red wire on your stereo to a fuse that gets power when the key is in acc

Thanks for the replies.

I think the red wire to the fuse box is the answer. I was talking to an installation technician today and he suggested the same thing.

yep. Done it before on a few gm's/pontiacs

Tried it and it works fine.
