I've searched here and google and can't find it. Does anyone know where I can get an internal schematic for a 93 Ls pr4 ECM. It should be the same as the 94-95 p75 ECM. My grounding output is dead at the ecm. The car runs when the main relay is grounded at the ECM. I need a component schematic to track down the problem instead the ECM. Thanks.

 

i called rywire to day hes said hes got info on his web site didnt check though

 

He's just got swap wiring info. No internal ecm stuff. thanks though
