I have a aftermarket Sony CD/Reciever, I read an article about snipping the 12v + wire. It is confusing, I have tried cutting some wires, doesn't seem to work. At one point, I saw an attachment online that would fix the problem, but I was looking for something else and ignored it. Now I can't find it. Any clues, suggestions, directions?

Not sure if you mean the plug is cut on the car or the radio. The colour code is pretty uniform , so its easy with a meter to identify permanent 12V, switched 12V and ground. Whats left will generally be speakers and aerial power lead if you have a power aerial.
you have a faulty alternator by the sounds of it, try this simple test, : test the voltage of the battery with the vehicle off with a simple multimeter, it should read just over 12v then test it with the car running, it should read around 14-14.5 volts if it still only reads 12v then your alternator needs replacing.
Try crutchfiels web site.I put a sony in my 95 and just had to wire the GM adapter to the radio.They sent me everthing I needed including antena adapter and face plate adapter.Even if you didn't but the reciever ther just call them and they will tell you what you will need.
From the factory wiring there will be a red/white wire with a constant 12v and an ignition switched 12v wire which is red/gray. Hook those to corresponding wires on the aftermarket wiring harness. You may have the constant and switched wires backwards. Also the antenna trigger wire (usually blue on aftermarket radios) should be hooked up to the green/red wire on the factory harness.

the best thing i can think to do in you case is find out if you are loosing the 12v (unlikely) or the ground (more likely) one side of the injector will have a constant 12v. if the 12v is dissapearing under the load then just snip the wire and tie into one of the other injector feeds. they should all share the same fuse anyhow. if it is the groung pulse dissapearing just snip the wire by the injector and the computer and run a new one. shure it might look funny outside the loom but it eliminates all other possibilities. if the problem persists then you are looking at a connector fault or computer.seeing that you have replaced everything else this should get you back on the road. feel free to write back if you have any questions.. dustang
