I cut my stock stereo harness and want to hook up a aftermarket CD player but I can't get any power


Power comes from 2 spots. Usually the orange wire(B+) goes to memory. You have to splice into an ignition on wire to power the radio. I splice from the A/C controller.

How do I fix the clock display on my 1999 Pontiac Sunfire?


It appears to be that the radio clock display has malfunctioned, and is due for a replacement radio, which could be an aftermarket or oem radio, maybe found at a junk yard.

Tools required for oem replacement radio, torx keys set.

Before working on the radio or other electronics, disconnect the battery cables with 8mm wrench.

Replacing the oem radio is much easier, if you obtain oem radio, compared to aftermarket radio, due to being direct fit.

The radio is same for 1995 to 1999 Pontiac Sunfire and the Chevy Cavalier, regardless of sub models, such as SE,GT, VL,VLX,Z24. etc.

Parts needed for the the aftermarket radio install :Stereo assembly, stereo wiring harness adapter, radio antenna adapter, and dash install kit.wiring diagram for the wire colors / functions, along with tools, such as torx key set, screwdrivers,wire crimper, wire stripper, double ended wiring connectors, hair dryer.

The oem stereo removal video is for the 2000 to 2005 Sunfire / Cavalier, but are the same or very similar procedures.

Im installing an aftermarket stereo in my 2002 Grand Am.. I bought an expensive harness and its not working.. I have the radio working, but the ignition wire from the radio is hooked up to battery...


This vehicle does not have a switched power suppy in the factory harness. The orange wire in the car harness is a constant 12 volts.
To resolve connect the 12 volt power supply from the head unit to a switched circut at the fuse block and this will resolve your problem.

My 2004 Grand Am GT Stereo Issue


I had the same problem when I changed out the factory cd player. I finally found the problem was that grand am gt cars have a couple of amplifiers with crossovers in them for the speakers and the after market stereos put out sound that has been slightly amplified already and when you hook up your new stereo to the wiring harness your sending amplified sound from your stereo the the factory amp then to the speakers this sometimes messes with he sound and clarity of the sound. My car is 2002 and the factory amps are located 1 under the glove box and 2 in the trunk behind the carpet on the drivers side. The amp and crossover in the front is to split the signal for the door speaker and the tweeter by the mirror and the amp in the trunk is to split the signal for the two way speaker in the back by the back window witch if they are like my factory speakers have 2 wiring harnesses connected to each speaker. the only way I could get mine to sound good was to run new wires from your stereo directly to the speakers and bypass the factory amps. This may not be the only way to fix this issue but it was the only way I could figure it out. I hope this helps

Wiring difference


If your installing a stock radio/cd player from another Dodge the wiring plug is the same and will fit.If your installing a aftermarket radio/cd player(JVC,Pioneer,etc)you will need to buy a adapter plug that wires up to the radio and is a direct fit to your factory wire harness,so your not cutting your wires.When you buy the adapter plug it comes with a wire diagram of which wire is what.Your aftermarket radio should have a diagram also,either on it or in the manual.Hope this helps you.
