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.

My car radio is not turn off when the car is turn off


This could be an issue with the ignition wiring. Most radios have 2 feeds. A 12v permanent live (often a red cable) and a switched 12v from the ignition (often a yellow cable). If the switched 12v is wired the wrong way round or linked to a permanent 12v then the radio won't switch off when you remove the key. Could be the ignition switch itself stuck on all the time also.

Why my car radio still on when the car is turn off


It is wired up so that it is not turned off by the ignition switch. Some cars are wired up this way. Some people put wiring on purpose to have the radio mot go through the ignition.

You will need to connect the pioneer unit to a switched ignition wire from the ignition switch. The 2006 GM factory radio only has a constant B+ (orange wire) and ground (black wire). The factory radio turns on when the Body Control Module (BCM) sends the radio a turn-on signal (on a data communication line) when the key is turned on. Your pioneer unit won't talk to the truck's BCM, and will need you to wire a switched B+ feed to it that turns on in the ignition accessory and run positions.

Faceplate has not illumination


I'm not sure what you mean by extra red wire. Are you saying that there are two red wires? Generally most radios these days require two power sources. The yellow wire for most after market goes to a constant power source and the red wire goes to ignition or switched power source. Both wires need to be hot in order for the radio to work.

1. Not sure what color on your ferrari is the wire to connect radio + to but with a voltage tester it shouldn't be too hard to find one that has power when ignition is switched on 2. ground to any metal part of dash that is bolted or welded to chassis should work well. 3. power antenna should be connected to the wire from the radio that has power coming out when ignition is switched on and radio lights up. Again use volt tester to check which wire has power when radio on!

First of all, the Bose amplifier needs to be activated when the after-market head unit is turned on. This is done by connecting a activation wire (often called a "remote" wire) in the factory radio plug. Usually this is a dark green or orange wire in the main radio plug, but in Onstar-equipped vehicles, the remote wire may be pink or orange in the smaller, secondary plug. In either case, the wire must be connected to the blue/white remote output from your new head unit, in order for the Bose amplifier to turn on.

I have a newer radio and want to install it, but isnt sure which wires connect, they are different colors


use a volt-meter or test light to find the positive supply power from your vehicles wires, and the ground wire too. attach those to the new radio's power wires (and attach the new radio's ignition power wire, or switching wire to the positive power wire from your vehicle too). The point will be to get power to the new radio so that you can do a trial by error to find which speakers turn on when you connect them. Just follow the sound! after you have found all the speaker wires. the last thing is to find which wire from your vehicle needs to be attached to the ignition wire on your radio. This wire makes sure your radio is off when your keys are turned off so not to drain the battery. if you cannot find a switching ignition wire, run a wire to a connection in the back of a fuse panel connection (which you can test any connection with your volt meter to see if it shuts off with the key.

Radio turns off in starting position


this look like a low battery and every time you try to crank your car it takes more power and kill the main power to the radio
solution # 2 the radio as 2 power wires one is always hot ( with current) and the other is connected to the ignition switch if you have replaced the radio those 2 wires maybe are connected backwards the one that goes to the switch is probably connected directly to the battery and the one is suppose to be always hot is probably connected to the switch if you have the original radio have your battery tested and if is ok then try get a haynes book at any auto parts for you car and try to follow the wire that is always hot normally is a yellow or orange wire
solution #3 this apply only if you car still have the original radio
turn your ignition switch to the on position but don't crank your car and turn your radio on select a radio station then turn your ignition key off and wait 3 minutes then turn your ignition switch on again with out cranking your car and the radio should be in the same radio station you select if this test pass then chances are is your battery getting low and if this test fail then the hot wire has a blow fuse look for the fuse inside the hook let me know what happend and good luck
