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?

Re: After market radio connected to a 2003 Chevy...
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.

You need to connect the red wire to a switched power source. The radio will not work of there is no power going to both the red and yellow wires. Yellow should be going to a constant power source (a source that is still hot when the key is off) as it controls the memory for the clock and preset stations. The red wire should go to a source that turns of when the key is off (accessory or ignition).
Hello my name is Israel and I would be glad to help you. ON the after market radio you will need to connect the yellow wire to a battery (+12 volt) source. Your best option will be to connect that yellow wire to the fuse block on the connector labeled as "bat". Good Luck and please rate.
You will need a wiring harness for the model truck you have, plus a filler kit. The filler kit is what the radio will actually attach to and fill the space left by the factory radio. Follow the diagrams for wiring from the harness and the aftermarket radio. Generally, there are 8 wires to be connected for a four speaker system. In addition, you will connect a ground wire (black), a yellow wire (constant power), a red wire (this is to turn the radio on and off with the ignition), and a solid orange wire (illumination). Because you have a GM product you will also need an antenna adapter. All these things can be purchased at Best Buy, or WalMart.
first of all what vehicle is it, because if it is a 2003 gm or later you might have to run a separate power wire to your red wire on your stereo. but if it isn't a gm. disconnect the wire harness from the back of the radio and make sure you have a constant 12volt to the yellow wire and 12volts on the red wire when you switch the ignition key to on. use a test light or a multimeter for this. you can find either pretty cheap at wally world or an auto-parts store.
sounds like you have a problem with the radio not your speakers and as far as schematics you may need to have somone check your radio out check the harness make sure its pluged in and secure make sure your connections are secure comming out of the harness your rear channel wires are green and purple so hope that helps
on the 1986 chevy coming out the ignitiion wire is grey the battery wire is yellow and the ground is black. On the radio the ignition wire is red the battery is yellow and the ground is black. I found the info on the truck in an old repair manual and the info for the radio in the paperwork that came with it. Anyway once you hook these three then you can test to see which speaker wires go to whick speakers. Take any two sp. wires from the truck and hook them up to any speaker wires on th radio and see whick speakers play. For me, I looked behind my seat and the wires were showing. yellow + and yellow/brown -RL. Light blue+ and dark blue - RR.
