1993 4,3l PCM Pinout Chart
Hello everbody!
At first I´m new here and so I want to introduce myself. My name is Michi and I live in Austria, so excuse me when my english is not the best. I have an ´88 Chevy Blazer 2,8l (5gear manual) and I want to swap to 4,3l. I buyed the ´93 4,3l engine with transmission (4L60e) and wiring harness.
Now my problem is the former owner cut the wiring after about 6inch behind the red and blue connector of the pcm. I searched a lot for a pinoutchart and I found this one : https://troubleshootmyvehicle.com/gm...in-out-table-1. All pins of the wiring scheme match my red connector, exepting B16-Brown-EGR pintle. My blue connector matches nearly none pin of the wiring chart. Maybe somebody has some tips or the right pinout-chart for me.

Try finding the factory manuals (2 books or CD-ROM) at rockauto.com - section literature for your engine.
Else PM me should be able to provide a 94 schematic. AFAIK pretty much unchanged.
