Hi All! New here!
I need a wiring schematic for the powertrain on my 86 D21 pickup with the Z24i engine. Anyone know a free source for this I have two generic manuals but they dont have complete schematics just small bits and pieces related to subject being pointed out. I have a drivability problem that seems to be electrical but need a good diagram to trace cuircuits to the ECM.

Thanks for any help!
