After reading and a quick trip to a local pull it your self JY

ECM / Harness /Dizzy (useless) / sensors

It took over 2 hours at JY to carefully pull this tangled mess without breaking anything in the process. The firewall grommet in this B body used epoxy like filler to keep everything together - nasty to remove.

After another 2 hours the harness was hanged like a deer for cleaning.

Removed wires and vacuum lines used by AC control circuits

Final harness, arranged and labeled

Surprisingly enough wires were in excellent shape - no breaks this was a low millage car. I did had to replaced several connectors - broken tabs and shorter overall runs. However in my next conversion I will get new harness - just to save time! Initial harness fitting:
