You're looking for 2.54mm (.1") "DuPont" style connectors (just google it). There's a special crimping tool for them that takes a while to figure out how to use well, and you buy the pins and the housings separate. You can get housings in different configurations, 1x1, 1x4, 2x4, etc.
Personally I would be careful with which LED and which board.. I mixed GGG's electric ice LED's with an Ultimarc UIO and after a few weeks the LED's started to degrade (some colors got dim on some LED's).. The LED's were rated for a slightly lower current than the regulated board kicked out (don't recall the numbers but I think it was something like .7 ma too much current). Unregulated controllers (that require resistors inline) don't have this issue, you just match the voltage to the LED and use the right resistor and no worries. The Ipac UIO is current regulated though, so no matter what resistor you use it will adjust the output to send the same amount of current to every LED. Great if you have the right LED's, not so great if you don't.
