Installation kit 02 s10
OK, now with that out of the way it, what you need depends on wether the car has On Star or not and may have an upgraded audio option, not sure about the S-10's but other trucks around those years had a standard audio using the headunit for power and other models, usually the ones with Onstar, had a factory amp.
I would say go to the Metra Dash Kit or Scosche website and walk thru the vehicle options and see what parts it lists, then get the single din dash kit (typically has a pocket) and the appropriate wire harness, or just go to walmart and find the kits listed for your model year like everyone did before the internet existed.
