the ones i have are for a 1990 (tbi) and your signature says you have a 93 which has mpi aka the wiring is different.  if im assuming something wrong and you need the tbi stuff i can email it to you. you can also find wiring diagrams at autozone.com if you make an account (they aren't the best but they will get you by) also if you go to the FAq they have a link to a factory service manual which i be leave has wiring diagrams...  last but not least you can google search "s10 forum wiring diagrams" or something like that and there is a thread for requesting  wiring diagrams and the guy will email them to you...

I've run the search and looked in the FAQ's and have been looking all day and just can't find any diagram that shows the wires that go down to the bell housing on the tranny. I can shake that wire and the engine dies and I don't know what it's for or why it would cause the engine to die. I'm gonna keep digging. Thanks

that wire is probably for the crank position sensor.it is mounted on the bell housing and reads the crank position off the fly wheel and without it it motor would die...

I finally found it on another site and I believe your correct. I really appreciate you helping me out. I know it's aggravating answering stupid questions but when it comes to wiring and diagrams I'm pretty well lost.http://www.4x4xplor.com/cps.htm

Make sure that wire is tied down, it gets a lot of heat from the exhaust.

Not sure if this helps, but I had an electrical problem with one of my BMW's when it wouldn't stay running and when I hit the brakes everything went haywire. I knew it was a charging problem so after replacing the battery, alternator, ground cable and battery cables the culprit was the battery light in the dash. That light that comes on when you turn the key before you start the rig. That burnt bulb was the missing link to complete the charging circuit. I was pissed, but at least figured it out. Have no idea if AMC/Chrysler did the same thing in the Jeeps, but its worth taking a quick look to see if there is a battery light in your dash when  you turn the ignition on.
