If you have oil in your harness than you definitely have a problem! The detergent in the oil breaks down the plastic insulation on the wires making them soft. Now heat and vibration from the motor will cause the wire to rub and expose the copper wire. In time this will cause the wires to melt together making them hard and brittle. There is your short! This problem is what took out your ECM. No problem we also offer Test & Repair Services for your ECM PCM TCM etc..
