[V8] Can someone confirm pinout of '90 V8 Engine ECU

[Steve Eiche]

I am testing a '90 V8 engine ECU on the bench, but I don't have wiring 
diagrams for the V8. I would like to verify the following connections:

Vbat: pin 18?
Ground: pin 19?
Ignition: pin  27?
L diagnostic line:  pin 13?
K diagnostic line:  pin 55?

TIA!
