If your jake brake harness is leaking like that your gonna want to pull the valve cover and clean it up and seal the harness pass thru with silicone sealant. You have to keep the oil from getting into the wires themselves. Also pull your ECM connectors off the ECM and see if oil has wicked its way all the way down. It very common for the oil to run right down the wires all the way to inside of the ECM. Clean and dry it if so.

It happened to me.

Listen to Chamberpains.

All that oil, and there's probably some fuel too, is real hard on the wire insulation also. Makes it very susceptible to cracking and wearing through easier. Just ask me how I know...
