1996 5.3 s10
This thing is nothing special just a budget minded swap. We used as many 4.3 parts as poss. We also built the harness using lt1swap.com. We used a walbro 255 pump. We also deleted the a/c and the power steering just to make things a little easier. Want only the things it took to make it run. During all this we also removed the abs and the air bags. We used the factory dbw throttle body with cruise control.
The engine ready to meet its new home


The truck before the swap.


Three hours after the start


Frame cleaned and painted ready for engine. This was the night after the last pics.

And the truck 6 hours after starting the swap. This is where the fast pace work stopped.

Walbro 255 pump installed.


The engine mounted and started runnig some stuff.

Milled the factory temp sensor down form 1/2"npt to 12mm to fit in the pass head.

Mounted 16"electric fan and summit overflow tank

Had to frankinstien the gas pedal to fit. I used DBW.

Got the truck back together with just wiring left.

This is a first for ls1tech.com i would say

Hi I'm currently trying to do an ls swap on a 96 S10. I'm having trouble trying to find out how to hook the LS harness into the trucks harness such as the C100 plug. I'm needing the pinout for that plug and any other plug that u think I may need to tie into. Could you please help me out?

I dont have an answer for you, but i will say you might get more help creating a new thread instead of bringing 1 back up thats 6-7 years old.
I can tell you the wiring isnt bad, go buy a haynes manual for your truck and it should have the schematics in it. Alot of other useful stuff in it too. Then go to lt1swap.com the engine side
