Don't worry so much about oily ECU M-connector, it's the contaminated Lambdas sensors that help generate ECU faults.
Whatever oil is already loaded up will keep slowly traveling to the next splice... Replace the cheap-plastic CPS sensors 4x $50Ea. as soon as convenient.
Get your Lambda on pigtails + seal each of the connections individually to keep oil from traveling through the pigtail.... else you know where this is going.
Do not hose down your engine clean with water - The harness electric connectors are nearly waterproof and best left dry or RTV-siliconed.
