Shhhhh, I have the laptop for a minute. I can help a bit. In mitsubishilinks there is a manual called Raider/fsm/1989/Powertrain Diagnostics located here and on page 25 with a listing of all the electrical connections. I have that FSM downloaded, but I have no idea how to make that one page show up here. That page has all the connectors that you can print out as a checklist and do the vinegar and distilled water cleaning

Thanks again to Bill for www.mitsubishilinkscom.

The only thing not covered was the cleaning of the ECM. Google and YouTube weren't a whole lot of help with that.
