Can anyone confirm which boss is the proper orifice for the oil pressure take-off?

Mike,
can you confirm if it is the red or blue one in the photo below? I am having a hard time figuring out which one it is. It looks like I have a threaded plug in the blue hole that would come out with an Allen wrench, but I am unsure. I suspect it is 1/4" line from the boss to the back of the oil pressure gauge.
