I had a piece of black tape over the one in my Probe as it kept flashing, but I think the rules were different then.
Surely the build date from etis would be more helpful than the reg date?
It goes without saying that anyone trying that method would do well to avoid doing this to the yellow-sheathed wires.
However you go about doing this, you need to know not to touch or interfere with the yellow loom. It is completely seperate from the main motor/heater loom.
