The aftermarket reverse harness should be mrked I hope that helps

Before you put power to this contact the manufacture of the unit for proper application so you don't short it out or start a fire.

Pick up a 7-to-4 adapter made especially for GMs and plug it into your existing 7-connector socket.

best place for stock wiring harness would be from the dealership. hope that helps.

buy the wire harnessconnector, it will save time, it plugs into the factory harness. then the colors should match those of the aftermarket radio.

YOU NEED THE HAYNES REPAIR MANUAL IT HAS AUDIO SYSTEM DIAGRAM.IT HAS ALL RADIO SPEAKERS WIRE COLOR AND RADIO WIRE COLOR.

BEST BET IS TO GO TO A STORE THAT SELLS &INSTALLS.... I,VE HAD THEM MAKE A COPY OF A SCHMATIC BEFORE... ,CHARLIE

The color codes will be different so when you take the harness off the 95 make sure that you label ALL the connectors to make it easier to install it on your Blazer. You may also have to change some sensors or switches up to 95 so that the harness will fit. Label all the empty connectors with their location in the 95 because they will be for options that may or may not be on your Blazer. If you have to access a wire diagram to complete the job then use the 95. DON'T let someone else take the 95 harness out for you andtake a rough diagram of your truck with the plug-ins marked for location and # of pins for wires. Basically it should fit but attention to detail is a must.
Also check out faxonautoliterature. They list GM service manuals but also GM books for engine interchanges that may prove to be very helpful. Hope this helps.

they are your speeker wires. the best the to do is to hook up the colors that are the same color to the color wires on the back of the radio. dont hook them all up at once two colors at a time.by doing this it will let you know what speaker you have hooked up.

Can purchased an adapter kit at Best Buy or Circuit City that is color cordinated with the factory wires for about 12.00. This will go right into the factory plug.
