Is the unit really 5" x 5" x 5" or is that the box it comes in?

It is no where near 5x5x5" the unit itself is more close to 1x1x1". Be aware though when I purchased this unit I received a dual pole and not a single pole as advertised (i received a relay with 5 prongs instead of 4) and still have not received the right model after Amazon provided 2 more attempts at reimbersment. Though for my application it can still be used (just slower switch reaction do to no power being provided on the 5th prong)

Are these relays suitable for outside the cab of a vehicle. It will receive light moisture at times.

I installed mine under the hood.
