Does anyone know where I can find an under dash or cluster wiring diagram for an 02 Blazer?

There are yellow and a white wires that are laced together that I need to know where they go.

thanks

 

i believe yellow are usually associated with airbag system

 

If they are twisted together they are data lines, don't untwist them.

 

Thanks,
but where do they go??

whoever installed an aftermarket radio hacked the harness.
and this is my wife's car.

 

A picture would help, is it part of the original harness that plugs into the back of the radio?
