5 pin relays are double throw relays. They have a normally closed pin that will power something when the relay is not active and then the normally open pin which will power something when the relay is active. If you do not need this, then you can get the 4 pin.

well the easiest would be to put the switch on the ground wire. If it is a short ground, 18ga should be sufficient.
