ECU pinout on 1988 80q 5 cyl

[blarson at zeiss.com]

Are the ECU pinout diagrams located anywhere on the web for a 1988 80q 5 cyl 10
valve?  I would like to check for power and grounds on both the timing and fuel
injection ecu's and this information would be very helpful.  Also, if anyone
knows the location of all of the ecu grounds under the hood on this particular
car please let me know.    Also, I would be interested in purchasing a used
Bentley manual for the 80/90 series if someone would like to sell one that they
are no longer using.  Please reply directly as I am on the digest.
Thanks,
Brian
