Candyman,
Looks like they did a really nice job installing them on your rig. No doubt they will really come in handy for you.
I use one set of mine to run my Grapple on my FEL. I have 3/8" hoses running to the front of the tractor for it. I use the second set for my Top Link. The third set you see with the Jumper in the photo are my connections for my Woods Back Hoe. I'm considering building a log splitter and using the back hoe connections for it so I can run the splitter from behind the tractor.
They should come in real handy for you. Nice work!
