Match your Black, White, Green from the cord to the wires on the ballast and then take the 2 blues to your light. It doesn't matter which way the blues hook up or the fixture would've specified it. As for the wire nuts, you will want to get a roll of rubber tape and use this as your first layer, then use a high quality electrical tape (super 88 or super 33) as your second layer. Stretch the rubber tape somewhat when you wrap your wires and wire nuts. And as someone else already said, you will want to extend the blue wires with some jumpers to the white wires on the pendant to keep your ballast as far away from the water as possible. I mounted my ballast under my stand and used a NEMA 3 rated weatherproof box with a rubber chase bushing to keep any possible leaks off the ballast connections. Good luck, and please make sure to be careful when dealing with anything running off of a ballast. These MH ballasts produce a voltage of around 350, which would really zap you even at only 1.8 amps
