s10 Wiring Diagram

I bought a '87 s10 that somebody put a '93 motor in and I am in desperate need of a wiring diagram. I bought a couple of repair manuals and none of them help because the print is to small if someone could please email the diagram to me I would be very thankful.

Bought a 91 S-10 and am having trouble getting it running. Read online about someone having a similar problem but have had no help yet. Can get it to run for a few by feeding fuel in through the throttle body but other than that it just turns over and will not crank.

Any ideas ?

I have a 1997 chevy s10 4x4 with the 4.3 liter. I statrtd to have problems with what seams to be my ignition switch. The truck actually cranks the engine in the run position on the switch. I changed out the ignition switch harness and thought it fixed the problem. Wrong it appears when it is hot out side this starts to happen. Is there a relay or contact switch somewhere else in the dash of the truck that controls the starter and fuel pump?

Truck is 1987 S10 extended cab manual shift engine two wheel drive. The wipers quit in todays rain and I have not found the fuse box. Before I start to remove dash panels does anyone know where the fuse box may be situated?

I also can not find any wiring diagram and bought the truck used so have not found a manual, nor a wiring diagram. Can someone assist with a link to information source or directions please. thanks

Ladies and Gentlemen, I agree with all your posts about Jacob's inquiry. The wiring diagram for almost all Chevrolet vehicles have the same pattern from the Automotive Electrical Engineering department where it is noted that the Chevy C35's to Chevrolet Volt has some similarities on their electrical composition.

Check out this after market part:

Took engine out of 95 s10 and put it into a 96 s10, 2.2 engine, changed complete underhood wiring harness and computer but can not get engine to fire. Can not find a wiring harness diagram for a 95 s10. Can anyone help?? Don't know how to check what wires should be hot since this does not have a distributor, just a coil pack.

I need to find out how to put on a wiring harness and where the wires go on a Chevy S 10 pickup 2.5 4 cylinder. Can you send me a picture or diagram of how to do this? It has 2 wires big enough to go on the starter cable. One may be a ground and one may be a hot. That's the only two I can't figure out. Thank you for your help.

I think it represents the frustration people have with their cars, and the auto industry! Of course some of the questions do get good answers and several of them at that!
