Need 87' Gn Wiring Diagram



Hello, I am in need of an 87' GN wiring diagram. I have a problem with my ECM or spark timing box and have to trace wires individually. Can someone send me one or a copy? I will send it back ASAP, if needed. I am trying to get it to my Buick mechanic, after hours. The sooner I get one, the sooner I am back to driving my car. Thanks Coach
