I don’t think any of those connectors will go onto the “ wrong place” , Bishop.

After I get a coffee I’ll take a picture of my 99, should be the same. It’s only 0545 here!

Look closely at the 2 connectors. The one in your picture closet to #1 has a raised notch on the connector that lines up with the slot in the relay. #2 does not. #2 if I recall plugs in down the side of the back of the radiator.
