I am wiring my whole house, and my cable guy used yellow, gray and blue runs. So I got blue and white cat5 plugs and yellow cat6 plugs. So far I've installed 5 of these blue cat5s, and all connected without issue, the caps lock on, and they lock into the wall plates (that I also got form Monoprice) solidly. Evereything is going perfectly, so I am very pleased!
Finished wall plate with blue cat5e, white cat5e, yellow cat6, and coax. All from Monoprice.
