I have had some problems with the wire conversion harness for my car (obd2-OBD-1). I am thinking about caulking the conversion harness in order to keep those connections from loosing continuity. A few months ago I was driving down the road and suddenly I lost a cylinder. It sounded like I was driving a BAD ASS WRX. It turns out the number four injector wire was getting pulled out by the passengers foot. I have since moved the wires into a more secure location however I do think that RTV is not a bad idea.
And yes it seems like you did your research.
