i have a base system/car as well

 

I would not rely on "best buy" to find you anything.

You should visit scosche.com or crutchfields

 

Cool, I have some questions maybe you can answer. Made another thread here: https://www.chevyhhr.net/forums/show...852#post239852

 

I saw a wire harness thru Crutchfield. That's where I am going to Purchase mine. Of course the head unit also. I was told it will keep the bells and chimes. I will go with the install card and have the installer promise to keep the chimes and bells, or back to Crutchfield it goes. they already said they will refund all my money. They have always kept their word on refunds.

 

Try boomJ.com they had the best price on my harness with OnStar and premium stereo options.

 

The pink wire is ignition...not ACC. To get ACC you need to go to the steering column and get the brown wire. just an FYI.

 

FYI most people on here still use fuse taps...very weak in my opinion. if we showed them how to catch accesory and then boost the signal with a relay half of them would torture that small wire until it was no longer useable. why have them go thru all of that?

catching ignition is much better than catching the fuse tap.

 

Cructhfield has a wiring harness. Its, Pac C2R Gm11. I ordered it today Suppose to keep all chiimes and bells. If you use this code it will save you $20: P74a5-1qudu-74t08. I also ordered a head unit and powered sub woofer......
