Re: cel issue
ok um the only thing i can tell you is to get ahold of the place you got the OBDII to OBDI converter from and ask them what wire you ground out to get the codes.
i had to remove a ECM harness from a 94 Teg for a Del Sol once and i can tell you that there are 3 wire that don't go to the engine bay connectors
Wire 1 gets 12V+ to power the ECM
Wire 2 Sends 12V+ to the dash for the CEL
and Wire 3 When connected to ground Makes the CEL blink codes and lets you set timming.
so you had to have some way to set timming and if you know what to do to set timming then that wire is the one you short to get the CEL codes

Re: cel issue
Read the Diagnostic Trouble Codes Without an OBD2 Code Reader
#1
Locate the 16-pin data link connector. Connect the jump wire to terminals 4 and 9 of the connector. Turn the key to the "On" position without starting the engine.
#2
Watch the "Check Engine" light. This light will begin to flash in specific patterns to indicate a 1- or 2-digit Diagnostic Trouble Code. The flashes will be long for the first digit, short for the second digit and blank if the digit is 0.
#3
Record all the codes given. The "Check Engine" light will display the codes in sequence and then keep repeating them in order. Refer to your repair manual to check for the meaning of the codes.
