Kerry,

That "something" next to the EFI computer is the serial port interface with the white coiled wire that you plug into your computer. Ken can help you with cracking the password if needed. Horrors, built in 1996 it says on the interface, you might be running Windows 95 and won't that be fun? Editing now, I misread the picture caption, and I have no idea what that APLW black box is. Thought you might be referring to the serial interface in the picture above

I just ran across this old thread and thought I'd resurrect in case this mystery is still unsolved. The black module with "APLW" label is an OE GM knock module. The scaling parameters for the knock control system were housed in this little module rather than in the ECM circa '85-'95. When ECMs were upgraded to 32 bit in mid '90s this content was moved inside the ECM. You'll need to retain the APLW module and wiring if the system has a knock sensor.
