Harness Adapter

Need another method for GM wiring harness for the stereo? I have a 2005 GMC Sierra, and want to put in an aftermarket radio I have. But Best Buy told me the wiring harness costs $150 because of some door chime thing. I'm not really concerned about the door chime. Can't I just get a basic harness adapter for like $10 somewhere? If so, could I get links too? If you actually need the $150 adapter. You should just bite the bullet and buy it. There is more to it than just the door chimes. Without it, you can do serious damage to the vehicle's charging and electrical system. Here is what the harness actually does. * Produces Chimes for door ajar, seat belt, low oil pressure, hi-temp, low fuel, headlights, etc.. * Generates 12-volt accessory output & retains RAP function * Uses genuine Delphi chip for seamless integration * Provides “Healthy Status” report to the Class-2 system Without the harness, you would have to find a switched accessory line and hard wire it yourself. The 2000+ GM radios are turned on by data. Not a 12 volt signal. Also, without the "healthy status" report, the vehicle's computer has to "relearn" every time you start the vehicle. In my shop, I've heard horror stories about "do it yourselfers" frying batteries and alternators as well as air bag issues. Your best bet is to get the GMCO harness. Here is a link to one that should work for you, As long as you don't have OnStar. http://cgi.ebay.com/SCOSCHE--GMLAN2SR-2000+-GM-Radio-Replacement-Interface_W0QQitemZ110341571077QQcmdZViewItemQQimsxZ20090123?IMSfp=TL090123112008r16081 Crutchfield is a good option. But, they won't give you that harness for free. If you buy the stereo from them, they will give you a discount on the GMCO harness. I think it still runs you around $75.

The Use of an ISO2CAR adapter when installing ISO harness products

A lot of aftermarket products are produced and designed to connect via a ISO harness, certainly the majority of Bluetooth car kits are provided with ISO connections as standard. These kits are designed by their manufacturers specifically because ISO is a standard connection used in a lot of older (and some more recent) vehicles. This system is used for several reasons, but mainly for reducing costs & to keep the products standard without too many SKU's (Stock Keeping Units) e.g. to remove the need for one kit for each type of vehicle or radio per manufacturer. You can see these will soon add up to a lot of different versions of the same products (SKU's).

ISO is a universal system that was used by a lot of vehicle manufacturers up to several years ago. The ISO connection is made up of a group of wires, which all have a standard and specific position within the harness. Each wire within the harness represents a specific connection to a device within the vehicle. For example the front right, back right, front left and back left speakers always hold the same position within the ISO harness no matter which vehicle it is located in. This allows the manufacturers of the products to produce a kit that operates in exactly the same way no matter what the device is connected too. By using ISO harness's you negate the need to piggy back and/or solder connections when fitting the product. 

However more and more manufacturers are starting to use their own wiring systems within their vehicles, this creates a small problem when installing the kits as connections will have to be made manually if the harness is different. So connecting specific speaker wires to the correct equivalent within the harness (each case will be different for the majority of vehicles) there is an easy alternative to this problem, the ISO2CAR adapter.

ISO2CAR wiring harnesses are made specifically to avoid this problem. There are around 20 to 30 different types of harness' available covering the vast majority of vehicles. The ISO2CAR harness is a connection device that will connect into the products ISO harness, then into the vehicle harness making the installation much more simple and pain free. The vast majority of vehicles now use their own wiring systems so ISO2CAR adapters are more important when installing aftermarket devices into your vehicle.

ISO2CAR harnesses can be used when the vehicle doesn't have an amplified or upgraded audio system, if this is the case a Drive and Mute cable will be needed where available.
