1988 Monte Carlo SS ECM Engine Wiring Harness Overview

Hope the focus is OK, it's an older camera. If anyone can chime in with the location of the idle stop solenoid, as well as the purpose of the melted mystery connector, I'd appreciate it. Please let me know if you want further details on any of the harness wire colors or details on any of the other harnesses. EDIT: I'm told the dark blue wire I was calling 'idle stop' really goes from the ESC to the knock sensor, so that's one mystery solved!
