I like to play with T&A

I've searched everwhere and can't seem to find anything, heres the story, my friend wrecked my truck, 1993 c1500 with a built ZZ4 and I had the ECM tuned for it.
I bought a 1989 K2500 and swapped the motor into it and was going to swap the ECM's out but it turns out the plugs are different so what i need is a wiring diagram for each that tells me what wires go to what on each of the ECM's so i can swap out the plugs s i dont have to swap the whole harness. ANYONE HAVE THIS I will paypal you some money for this info!
