Yesterday I was oiling the zergs and checking out the KDSS valves. Luckily with a little force I slightly opened them both. However, next to the valves I saw an unconnected plug for something. Any idea what is supposed to be plugged in that? I couldn't find any unplugged wires nearby. I assume its possibly for diagnostic or required for refill of KDSS fluid.
I attached a photo of it just for reference.
