There is none. At least I can never Find ecu schematics . The only schematics I've been able to find are for high end European cars.
Your best bet is to go to Pick n pull and grab a spare on. Then trace everything out.
I assume you have an oscilloscope if you're repairing an ecu.
If you can get the manufacturer and SN of the board you (should) be able to find the schematic.
Does the ecu just not work?

I had one from out of an 87 pickup 22re kicking around. Not sure if its still out with the remnants of the wiring harness or not. If you are interested PM me and I will see if its still around. If I do still have it I do still have it I dont have any use for it.
