 RJ-45 jack connector
I have to install some RJ45 keystone jacks to CAT-5 cables but I do not understand the markings on the back of the jack. The cables are wired blue, blue/white, orange, orange/white, green, green/white, brown, brown/white. The back of the jack has a sticker with numbers and colors that don't make any sense, and I don't know how to wire the jack. Could someone help? Thanks.

Dear Josh,

Typically the jacks are marked with color codes for the T568A & T568B wiring standards. You are to pick the color code you want to use and follow it.

See this web site for a typical installation video
