SSR Control Wiring Question (SOLVED)

I’m in the midst of hooking up the control wire for my SSRs to the 5v out on the Brewpi Spark and realized I’m not sure on the Brewpi’s 5v output which is Ground and which is Live. Does anyone know?

Thanks in advance.

Never mind. I see now its printed on the sticker that came with it.
