I am desparetly trying to figure out how to use this product. I have four lights that I want to hook up to the dimmer/relay pack but I can't figure out how to control the lights. I need to dim all four lights on and off all at once but so far all I can do is get them to turn on and off but on the programed chase. I inherited these products and I'm just trying to make them work. Any help would be wonderful thanks!
