Am I missing relays? Eatx, what is it? 96 Caravan

I recently purchased a 96 caravan and noticed the Eatx shutdown relay and Eatx backup relay positions in the PDC did not have relays plugged into the slots. What is Eatx and should I have relays in those postions. Also the fuse panel under the dash is missing drl#3 relay, anyone know what that is for and if I need it? Thanks

The relay slots may not be used due to options you don’t have on the van. Here is a link that you can go to and read about EATX.

The DRL relay slot is most likely for daylight running lights.
