Hi!
It depends on what kind of electronics you are using and what type of motors you have. I think most standard would be 4 wires on a stepper motor to RAMPS 1.4. You just need a four pin connector, and I believe it is called "crimp" style or something like that since it crimps the wires. Here is a 6 pin version that a quick search gave, I'm sure that site has four pin connectors in the same section. Good luck!
