were can a person get a 2002 S-10 4.3 L v6 Engine wiring diagram. I am putting a 50s Chevy truck sheet metal on a 2002 S-10. And I like to build a stand alone engine /transmission harness. It has the complete 02 4.3 running gear with automatic trans. fuel tank, pump and etc.

 

Use the harness from the 02 S10.

 

Yes using the original wiring sounds easy. But when you try to use it as it came from the factory, Its not on a car or truck that's 65 years older its not, Just to mention a few things Computer gets flashed so Vats are disable - vehicle anti-theft, No rear 02 sensors , No Egr , No speed limiter ,No emissions, Dash wiring , radio , and gauges after market and different . changed from a standard to a 4L60 E transmission , steering column wiring different, So as said Use the factory blazer wiring harness. I plan to. But still the 02 blazer wiring harness has lots of wiring front to rear and a lot of it needs to be deleted or sent to other places. That's why I was looking for a wiring diagram ( color would be nice) Or a stand alone wiring harness the some company made. I seen them for like your Chevy Ls 1,2,3 and 8 engines several companies make them, But I have not seen any for the 4.3 I do have a complete in tack, uncut 02 wiring harness, but most of it is not needed. Getting the PCM/ECU flashed is the easy part. Lots of people do that. But Thanks !

 

You are using the S10 chassis with the S10 motor and transmission and exhaust aren't you? Most of what you will be using will be from the S10, so the harness should work except for some of the accessories and gauges which you can work around.
