I found out that the harness was discarded for the 93 2.8 v6 that is now in the truck. I have the original ecu that I can install in the truck, and the plugs that plug into the ecu with all pigtails hanging out of them that they cut to remove the ecu. Now, I found a blazer with 2.8 but it is a 92. I really would like to make this thing fly. You mention switches and etc. and I don't quite understand what switches and how that affects anything, but am probably in for a lesson. Does anyone know if the 92 harness is the same as 93 on all 2.8 vehicles? Or should i go to a junk yard and look for a harness of a 93 s10?, and does it matter if it is an automatic or standard?
