i got some fog lights and i need to run the cords into the cab from the front. so if any one could help me in finding a whole in the fire wall i would be happy. but if there are not any the best place to drill one. thanks

 

On the passenger side under the upper carpet, you should see a rubber grommet with wires coming through it. You can run it through there. At least thats where I ran my wires on my 01.

 

Yep, pretty much the same place for all S-Series vehicles... My '85 S10 had it in the exact same place my '05 Blazer has it.

It's where the radio antenna goes.
