After market radio connected to a 2003 Chevy Trailblazer

My after market radio is connected with the wire hardness for GM, but it is not connect so that it turns of with the car's ignition switch. The radios (red) wire is connected directly to the battery which cause the radio to be constantly on. How can I fix this so that it shuts off along with the igniton switch?

Hi,

The recommended wiring is that the yellow wire (from the Pioneer DEH-P3900MP) be connected to an "Always ON" B+12 such as the battery's positive terminal. Additionally, the red wire should be connected to a switched/accessory +12 such as the ACC terminal of the ignition switch. Wiring it this way would switch off the radio when key is likewise off.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I PUT AN AFTERMARKET RADIO WONT POWER UP.


If your Trailblazer does not have rear seat audio, check the 15A RADIO FUSE in the I/P fuse panel. If your Trailblazer has rear seat audio, check 15A RADIO FUSE 41 and 10A HVAC B FUSE 36 in the rear fuse block. You may have to use a different adapter to get the radio to work.

What's the Motorola box under my back seat Chevy trailblazer 02 also I'm hooking a amp to battery where do I connect the amp turn on wire I guess it be remote wire


The motorolla box may be remnants of an old disk changer for the stereo. With an amp your power wire goes into the positive wire that goes to your battery, your ground wire will be connected to some bare metal close to wherever you decide to install the amp, and the blue remote wire will be connected to the remote wire that in on the wiring harness of your aftermarket radio ( I'm sure your not installing an amp with your stock radio). Good luck I hope this helps

No, make sure the vehicle key is in the aux or on position. If this still doesn't work, recheck the wiring. Also, make sure you have a good ground.

All i can really suggest is let GM check it out if they want to replace it, i would look into replacing it with a upgraded after market unit to fit in its spot. probably cheaper than dealer will charge.

Radio Console wireing


A decent auto repair manual for your 2003 Chevy TrailBlazer (such as Chilton's, Clymers, Haynes, etc...) with a complete wiring diagram should give you the color codes for the factory speaker wiring. You can probably find and copy the pages you need at your local Public Library too.
Good Luck.
