    Default 1999 Volvo Penta 5.7 ltr GSI location of Diagnostic Connector

    The Ecm label reads the following Module A 57T8 (L or I) 99R7. Can't find the Diagnostic Connector. The ECM appears to be a MefI 3 or 4. Can anyone help?

    Thanks I have the diagram. The only end connector I can find terminates towards the back of the port head and there are only two wires. I will double check this morning.
