My profile explains everything. I am a “diesel dummy” but need a little help to finish diagnosing. I want to check the harness from the ECM to the injector pump. I see where it connects to the injection pump then the harness goes into a main loomed harness. I have probably over looked the ECM but where is it so I can check the connector and pins. Any pictures would be a great help. Thanks

The ecm is on the block. It’s between, and a little lower than the injection pump (vp44) and firewall. 

Thank you. I will look today
