GMC Repair: hanging wire, full size chevy, chevy blazer


Question
I have a 92 full size chevy blazer and i discovered a purple wire with a white stripe hanging from under the dash. The wire has plastic connector on the end that says "p.e.d 22". Do you know what it might go to or where online I can find a diagram? I have looked at the repair book and the wires dont have numbers so i cant figure it out. Thanks for any help you can give me.

Answer
Hi Brody, You will need to obtain a wiring diagram of that section of the vehicle, if you know someone who works in a garage and has an information system such as shop key or motors it will be easy to find what this wire is for. Most vehicles use the same wiring harness for numerous vehicles, so that wire may be for a option which your vehicle does not have, but a wiring diagram is your best bet.
