Audio Systems: Stereo wire diagram, car radio wiring, car radio wiring diagram

Question
I kinda already went ahead and cut out the existing head unit harnesses in my friends 1994 ford explorer and, after hours of looking for an accurate color coded wiring diagram, I have pretty much given up hope. is there anywhere I might find a diagram for this? One that is clear?

Answer
This may be helpful even tho it is for 1995 model:

Using the wiring chart for the car and then matching it up with the wiring chart from the installation manual of the new radio unit you should be able to get it working just fine.

Good Luck.
