New Radio = frustration to the max

So, I recently bought a new car receiver from bestbuy (Model #KDR860BT ) and after pulling the front panel off of my 2005 Chevy Impala, I come to the consensus that I couldn't install this radio in the current format of harnesses that my car has by factory default. So, a trip to CarToys later, (and a horrendous quote that shocked me a bit) I was told I need a specific data retention harness. So, I suppose I'm more asking about what specific model this retention harness has to be and where I can get it? CarToys quoted me at $235 to install this radio into my car, when, if I could find this mystery harness, I could do it myself. I'm pretty well-versed with how wiring works as I'm a computer nut, which I'm glad I didn't go cutting into wires to fit into my new harness for the radio.

The instruction manual had a site that they suggested to find the vechicle-specific "wiring harness" and it was Metra. I looked there, and from what I saw there, there were only replacement parts to what is currently in my car. I'm a bit frazzled and could use some clarity!

Thanks in advance!

Does it have OnStar?

"You may need a data retention module to replace the computer chip that was inside the factory radio that communicates with the cars computer. These will help turn on that factory amp that keep the car data correct. The data retention modules usually have a wiring adapter with them." - From Car Stereo Head Installation | DIY Car Audio | Car Audio Installation

http://www.amazon.com/GMRC-01-Axxess-Non-Amplified-Non-OnStar-Interface/dp/B00032AIGG/ref=au_as_r?_encoding=UTF8&Make=Chevrolet%7C47&Model=Impala%7C451&Year=2005%7C2005&ie=UTF8&n=1077068&newVehicle=1&s=car&vehicleId=1&vehicleType=automotive - This is the DRC (Data retention cable) that you need. This is for non OnStar vehicles only, pay attention to that. Hook it up and splice into the harness for the radio. Boom.

That^^^ Good luck op.

 
Thank you both so much!
@LongThrow: By splice, you mean couple the wires from the new radio into the wires that the metra harness has? Or what exactly is that harness going to do? Because the pictures are not helping me visualize lol. And will that splice be as easy as coupling the wires with some electrical tape and some wire overlapping? And I'll need to get some sort of radio antenna fix thing too because the factory one does not fit into the new radio.

Head unit > Head unit's wire harness that was included > Data retention module.


Someone else might want to clarify on that.
 
so funny to see this on here b/c I see it all the time. should have just got the harness from Best Buy and got them to install it for you. they would have been cheaper that car toys but not by much b/c the module is still $150 no matter where you go.

Read the manual that comes with the harness to figure out what each wire is for and twist it together with the wire from the radio by matching the manual specifics.

A friend of mine had a harness to bypass this problem that was long enough to relocate the factory deck in to the trunk. It was kind of weird, but it worked and was cheaper than the other harness.

So then what you're saying is that the amazon link provided is not what I'm wanting? Because it definitely sounds like it is, and it's not $150..

The harness posted is used to keep access to all factory stuff like door chimes and stock amplifier wiring and such.

There is another one which is 150$+ that includes a screen for factory menu integration so you can control stock system features like setting remote start and low fuel warnings.

Then there is another CHEAPER that does not retain data link. All it does is allow you to install a aftermarket radio, but you will not be able to connect factory amp or change system settings like i said above like chimes and all.

No, don't listen to him. That's the right one.

Head unit in the trunk...? Okay..

So with this cheaper one I won't get a low fuel light? That seems a bit strange.. why would that information have to go through the radio?
