I really can't tell from the picture,but the jack plug has a "point" a plastic ring (probably black),then a long shaft that has the cover that screws on it. The point is the positive and that is the positive from your piezos. It will be the red wire. Solder the wire to the terminal that touches the tip. The long part of the shalt will be the part of the terminal that touches the long part of the shaft.

The outer metal part is ground,  the center pin is the signal...

OK thanks guys. Soldered up to the outer part where the piezo was wired and it cut the hum :)

What do  you  mean, cut  the hum, there should be no hum. Are your strings grounded?

No, they weren't, that's why I needed ground wire.

I'm glad you got it fixed. Two years ago I didn't know about the grounding of the strings either. I learned it from somebody on this forum. Keep it goin'. Keep buildin' (;-D)
