I'm sure this is discussed here somewhere so sorry if reduplicating but can't find exactly what i am after in other post I bought some of these Ray Wu 10w 12v floods and they have the three pin metal DMX connectors and a red and black wire. http://www.aliexpress.com/store/product/10W-RGB-DMX-flood-light-DC12V-input/701799_550394253.html I just want to connect them to one of my existing DMX boards from AVD. All my other dumb RGB stuff has the power lead and then the RGB leads connected to 4 core pigtails. So do I just cut of one of the metal 3 pin connectors and solder on one of 13.5mm 4 core plastic pigtails with the red power lead added in? What do i do with the black lead and can I just not use the other metal DMX connector if I'm not daisy chaining them? Make sense?
