How do u hook up for a two (2) wire hook up

If any of this doesn't make sense or you aren't sure just get an electrician to do it: If by two wire hook up, you mean you have an older home and the receptical box doesn't have neutral or ground in it: you'd need to determine if the box is grounded. If so then tie the green(ground) and white(neutral) leads to the box itself for grounding. If your home was built recently, the white wires are probably in the box and just pushed to the back, probably covered in sheet rock/paint and perhaps the bare/green/ground wires are there too. If you don't have a grounded box nor ground and white wires then you'd need to pull a new ground and neutral wire to the box, which would probably be best left to a pro. After you sort out the ground/neutral issues its a basic switch install: black wire on the switch needs to be connected to the always hot wire (probably black) in the box and the red wire to the lead that runs to the lights (the unit switches the red leg). Be sure to take a look at your box and determine what you have before you start wiring. If any of this doesn't make sense or you aren't sure just get an electrician to do it.
