kenr74;
This is not meant to be offensive. Do you already have the lights and the Motion detectors, if so do you know if they are low voltage or 110V? I don't know your understanding or your knowledge, but if you bought low voltage Motions you can't pass 110V thru them. Well you can but it only works once and for a really short period of time (JUST JOKING DON'T EVEN TRY TO MINGLE LOW VOLTAGE WITH 110V!)
If you provide me a list of what you bought I can probably give you a one-line diagram on how to wire it.
