What gage wire are you using? When using LED's, they have a small enough load that 30AWG is more than heavy enough, probably with about a safety factor of 4X.

Dupont plugs will handle the amp load, are fairly small, only require a crimp connection, and are available in a variety of pin numbers.

JST connectors are another good choice, they'll handle even more amps than a Dupont plug. I think Dupont plugs are rated for a couple of amps.
