SOURCE: Installing an aftermarket stereo, spliced the wires and have everything connected including the remote wire to the factory amp wire but still no sound.

There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps

Not sure I understand your question. Did you buy a harness adapter for GMC, or are you trying to just cut the connector off the factory radio and solder it to your CD player? If the latter, below is the color code for your factory wiring.

Trying to install a aftermarket radio in my 2004 Oldsmobile Alero I wired color it won't come on


You wired color ? Hooking up an aftermarket radio on your vehicle requires a special interface module , that may not be the name it's called . You better check at a stereo shop that installs radios . Your vehicles radio is connected on what is referred to as class 2 serial data communication network .
Class 2 Serial Data Link
The following modules use the class 2 serial data link to communicate with each other:
?€¢
The body control module (BCM)


?€¢
The digital radio receiver (DRR)


?€¢
The electronic brake control module (EBCM)


?€¢
The inflatable restraint sensing and diagnostic module (SDM)


?€¢
The powertrain control module (PCM)


?€¢
The radio


?€¢
The vehicle theft deterrent (VTD)

The class 2 serial data link also allows a scan tool to communicate with the above modules for diagnostic and testing purposes.
The class 2 serial data link on this vehicle is configured in a star pattern. There is no redundant path for the serial data to flow through. If a class 2 serial data circuit develops an open condition, the module connected by that circuit will not be able to communicate.
If not hooked up right the vehicle may not even start .

I'm installing a aftermarket stereo in my 2005 grand am se the wire harness adapter for my car requires I run the accessory wire to one of my fuses for whatever reason I need to know which one thanks


Are you aware of the fact that your factory radio is connected to the class 2 serial data communication network . You need a interface module to hook up to aftermarket radios . If you don't use this interface module your vehicle will not start an run an the warning chimes will not work .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:

New stereo hook up


You better read up on class 2 serial data communication networks . Does supply ACC voltage to anything . Your vehicle has many different control modules , PCM / ECM , air bag , ABS , BCM instrument cluster ,an the radio an some others . If you mess with or ground this wire your vehicle will not start or do anything .

The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. The serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps. This value is an average; class 2 uses a variable pulse width modulation to carry data and depending on the message it may operate faster or slower. The bus will float at a nominal 7 volts during normal operation. Each module can pull this lower during the transmission. The bus is not at battery positive voltage or ground potential during normal operation. When the ignition switch is in RUN, each module communicating on the class 2 serial data line sends a state of health (SOH) message every 2 seconds to ensure that the module is operating properly. When a module stops communicating on the class 2 serial data line, for example, if the module loses power or ground, the SOH message it normally sends on the data line every 2 seconds disappears. Other modules on the class 2 serial data line, which expect to receive that SOH message, detect its absence; those modules in turn set an internal DTC associated with the loss of SOH of the non-communicating module. The DTC is unique to the module which is not communicating; for example, when the inflatable restraint sensing and diagnostic module (SDM) SOH message disappears, several modules set DTC U1088. Note that a loss of serial data DTC does not normally represent a failure of the module that set it.
On some vehicles, if the powertrain control module (PCM) is unable to communicate with the vehicle theft deterrent (VTD) system after the vehicle has started, the PCM will consider the VTD system to be malfunctioning. The PCM will enter a fail enable state and will command the security indicator to illuminate. When the PCM is in a fail enable state, the vehicle will NOT stall or stop running. If the PCM is in a fail enable state when the ignition is switched OFF, the PCM will remain fail enable until communications with the VTD system has been restored. When the PCM is in a fail enable state, the VTD system is NOT active and the vehicle will start. This feature is NOT available on all GM vehicle lines.

You need a interface module for your radio to work . Go to a professional installer place an talk with them . Your vehicle may not have all of these modules , but most .

Class 2 Serial Data Line
The class 2 serial data line on this vehicle is a star configuration. The following modules communicate on the class 2 serial data line:
• The body control module (BCM)
• The digital radio reciever
• The driver door module (DDM)
• The electronic brake control module (EBCM)
• The front passenger door module (FPDM)
• The HVAC control module
• The inflatable restraint sensing and diagnostic module (SDM)
• The instrument panel cluster (IPC)
• The memory seat module (MSM)
• The powertrain control module (PCM)
• The radio
• The radio amplifier
• The rear seat audio (RSA) controller
• The rear seat entertainment (RSE) assembly w/U42
• The rear wheel steering control module
• The remote playback device-CD player w/U1S
• The transfer case shift control module
• The transmission control module (TCM) w/Allison Transmission
• The theft deterrent control module
• The vehicle communication interface module (VCIM) w/UE1

with the ignition in the "off" position get a test light and touch one wire at a time while cycling the ignition switch to the "on" position, When you see that the test light goes off when the ignition switch is in the off position then you found the hot wire, make sure you dont hook it up to the "alway hot " wire or you might drain the battery hope this helps.
