i have an 89/90 ECU for my 964 motor. found out my #1 injector isn't getting a signal to one of the leads. it's getting 12v power to it but no pulse. hooked up the noid lights and confirmed it. also confirmed continuity from the ECU plug (#17) is dead or not connected.

i need to trace the connections from the injector plug to the ECU and wondering where the connection is failing. doesn anyone know if there is a plug along the way that could have gotten corroded? can anyone point me to a wiring diagram for this pin out connector?

thanks in advance.
