Which connection? The dash is in the dash, the tail lights is in the rear hatch area...you can find a wiring diagram and info in a shop manual at the library...you need to make copies as they are reference only...:)
Dash lights and tail lights are on the same fuse.
Parking/tail/dash fuse
Loose connection.
Look under the dash to the left of the steering wheel.
These are on the same fuse. Check for a blown fuse.
Probably the Tail light fuse is blown. You also lose dash lights when this fuse blows also.
the DLC is under the steering column just behind the plastic dash
Should be the same circuit for parking/tail/dash lights
warning lights mean something is wrong and needs attention by a mechanic
check your fuse
No, this is not normal. You have a problem.
