I have a 1993 Chevy s10 blazer Tahoe, at the throttle body there are two cables ,one comes from the gas peddle and the other from a vaccum system. What is the vaccum cable called and what does it do?

cruise control? Im not sure if cruise using any sort of vacuum system though

 

The other one is the cruise control, leads to that vac container on the drivers side.

 

You all got it right, it is a cruise control cable.
Thanks,
Rich

 

You are welcome. Mine did not work since I got my 93 Jimmy. Recently when I was mess around under the hood I noticed that plastic jacket that covers the wire was not attached, so the cable was folding when the throttle was opened.

I have a curious mind, why were you wondering what this cable was for?
