Did the truck have the premium sound system? If so, you will need to connect the blue remote wire to the blue remote wire on the harness. You may also need a special harness to bypass the factory amplifier.

Yes, It's a very good possibility that you will have a few wires left over. Normally a wire for an aftermarket amp to be triggered on when you turn your radio on and possibly a power antenna or a dimming function that dims your radio lights when your headlights are on. It of course always depends on if you have a power antenna or not, or if you have an aftermarket amp or not or if you have the dimming feature on your car or not. These wires don't apply to everyone.
You will just match the colors between the wiring harness that came with the DUAL radio and the interface adapter that goes to your car. Make sure you use **** style crimp connectors. If not the wires could come loose or cause a popping noise or cause the radio to turn off while driving.
Other than that, installing an aftermarket radio is mostly matching the colors up between the two harnesses and crimping the wires together.

Basically the radio will fit but since harness differs between some chrysler products, you need to find the pigtail that will fit the Dodge harness and give bare wires to connect the Dual's respective wires. An example of this can be seen at http://www.hifisoundconnection.com/Shop/Control/Product/fp/vpid/2669860/vpcsid/0/SFV/30046

I have found similar pigtails at Walmart, Best Buy, and some autoparts stores. Crutchfield includes all this based on your purchase - just a thought.

This vehicle does not have a switched power suppy in the factory harness. The orange wire in the car harness is a constant 12 volts.
To resolve connect the 12 volt power supply from the head unit to a switched circut at the fuse block and this will resolve your problem.

The best way is to get a stereo installation kit designed for your car. It will have the surround for the new stereo to fit where the stock stereo fit. Also, it comes with a wiring harness that you connect the new stereo to then it plugs in to the stock radio plug. Most local automotive stereo stores should carry them.

ARE YOU AWARE THEY MAKE A VERY INEXPENSIVE ADAPTER HARNESS THAT HOOKS UP TO THE FACTORY HARNESS, NO WIRE CUTING,CAR AUDIO SHOP CAN GET THE ONE U NEED, ABOUT $12. HERE IS THE WIRING COLOR BREAKDOWN OF THE DASH HARNESS.

Hello dusashbrax,

The wiring color code for the 2002 Blazer is here. Just match up the function of each wire on the aftermarket receiver with the appropriate color wire from the vehicle.

A better solution is to purchase a vehicle specific wiring harness. Then you just match it up with the receiver harness color for color.

Hope this helps.

to the guy who is looking for the wire diagram, you can buy a wire kit for the stereo connection for about $60 from best buy or some other place like that. your car's door ding and some other things wont work with out it. hope that helps you some.
