I ended up just crimping the connections off the wires, twisting them, wrapped that in electrical tape, and then used heat shrink tubing. It works perfectly.
FYI for anyone thinking about overvolting, buy the metal optronics housing. I'm running 14.4 volts into a 35W MR16 and I melted, deshaped a few other housings but the Optronics metal driving lights are the best I've seen, I'm very happy with them and they're cheap and they got to me pretty quickly from JCWhitney.
Also, some advice... as far as the solux mr16 bulbs go, I would definitely recommend the 3500 or 4100k, they are PLENTLY white enough. The 4700k isn't neccessary and it also puts out less light.
