The car is made with "production-intent" parts, but for the most part these are all of the parts that will be in your cars-they put that intent in there just in case IMO. You can not omit DRLs but you CAN override them via the switch. It is spring loaded, and will revert back to auto, so you would have to override each time. It seems like most of you would only want to temporarily override in specific situations, so you'll be fine. The second vertical switch I will check if I remember correctly, a big if, it controls the length of time the exterior lights wll stay on after you shut off the car? I will check
