I am search everywhere for a diagram pinout of my ECU
1998 venture v6 3.4L
are they in repair manuals ?

 

You might find it on Autozone. You must register (free) to gain access to their online library. They do have schematics.

The Factory Service Manual, which will cost you about $135, has everything.
