    Which is the best fuse to run my switched power source. All the fuses I have found so far don’t have enough juice, or are not switched.

  • Reply ModifiedLife August 7, 2008 at 2:25 am

    Yaicu2, run a primary wire to your steering column and tap the pink wire (accessory switched power) in your ignition switch harness. Hope this helps. Good luck.

    What is the best way to interface an iPod iTouch (2nd Gen) to this radio?

    Jairo, there are some companies that manufacture interfaces that allow you to hook up an Apple Ipod to your factory Chevrolet Silverado stereo. Here is the Apple Ipod Interface you need:

    I don’t mean to sound so stupid, but what is the function of the switched wire, and will it make everything turn off when you open the door?

  • Reply ModifiedLife February 3, 2009 at 6:22 pm

    Legolis57, the accessory switched wire sends power to your radio only when the key is in the ignition and your car is on. Hope this helps. Good luck.

    I just bought a 2005 Chevy Silverado. I am trying to hook my amp up to the factory system. I have done many system installs in older vehicles but always had a wire at the head unit to tap into to.

    I have read many posts here that suggest tapping into ignition wires. I spend a hour or so today digging around the steering column but didn’t see these wires. In my 2005 would the wire I be looking for be Pink? If so where should I be able to find it?

    Is there any risk with tapping into that wire? I don’t need to cause any other problems in the process.

    Does anyone know if the blue Antenna wire from the head unit would have enough power to turn on the remote for an amp or if it would have enough power to turn on a relay if I went that route.

    Thanks in advance for your help.

    Blazen, use the pink wire in the ignition switch harness. This harness is usually located either in the steering column or towards the bottom side of the steering column. You may have to do a little digging in the factory wire looms.

    As for the blue antenna wire from the head unit, we don’t recommend you use the blue antenna wire from the head unit because it only sends a signal to turn something on when the radio is on but no signal when a CD is playing. If you need a wire to use to turn on the amplifier, use the radio switched 12v+ wire. That way your amplifier is always on whenever your 2005 Chevrolet Silverado is on and off whenever your 2005 Chevrolet Silverado is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck with your amplifier install.

    I have a 2005 Chevy Silverado Z71 with Bose and onstar. I just found out that there is no wire on the harness for illumination. Do you know of anywhere else I can tap into so I can get 12v whenever the lights are turned on?

  • Reply David April 2, 2010 at 2:54 pm

    I have a 05 Silverado with no Onstar. Does anyone know if you have to use the relay when installing an aftermarket unit?

    I am upgrading my stereo in my 2005 Chevy Silverado. It had a base stereo system, no CD or cassette tape, just AM/FM. I purchased a JVC – HDR40 along with a the Scosche DIN Mounting Kit (GM1583B) and the Scosche Wiring Harness with the chime kit (GMO9SR). After splicing all the cables correctly, I plugged it in but nothing. I reconnected the old AM/FM Stereo and it was dead. I checked and tested all the fuses in the fuse box, but now both stereos seem without power. Everything else in the truck works. I think I might have “blown” something in the factory harness route, when prior to the complete installation, I plugged the chime to test. The new chime came with a relay (12V 30/40A) but I had not plugged it into the adapter. The chime was working but it sounded like it was slowly “fading” then stopped. I thought nothing of it until I tried to get the new and old stereo working. Could I have blown a relay somewhere else, specific to the stereo? Everything else appears to be working in the truck. Any assistance would be appreciated!

    I would like to install an aftermarket head unit in my son’s truck and I would like to retain the steering wheel volume control. I know I have to have a device to tie into the aftermarket unit, but I need to know what color the wire is and where the wire is located that goes up to the steering wheel control. Thanks.

    I’m trying to find the best, yet most cost effective, option for playing my iPod or iPhone in my 2005 Chevrolet Silverado, with the factory stereo. I currently use a wireless FM modulator and the sound quality is horrible. I’m considering going with a wired modulator. Are there RCA Ports on the rear of the factory stereo?

  • Reply ModifiedLife June 21, 2011 at 2:39 pm

    Pat, we suggest you purchase an automotive auxiliary input adapter. This adapter will allow you to input any Apple iPod, mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

    I am putting an amplifer in my 2005 Chevy silverado and I am having trouble with finding a way to hook up the REM or remote on the amp. How would I hook it up? Through the steering column?

  • Reply ModifiedLife January 9, 2012 at 5:10 pm

    Michael, technically you could connect your 2005 Chevrolet Silverado amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2005 Chevrolet Silverado is on and off whenever your 2005 Chevrolet Silverado is off. Run a primary wire to your steering column and use the orange wire in the ignition switch harness. This orange wire will provide you with a switched power source. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good luck with your 2005 Chevrolet Silverado amplifier install.
