I'm planning the additional wiring in my garage so I was planning to connect devices directly with male plugs. A wall plate with female jacks would be neater but unnecessary. I have wall plate in the house and connect to them with patch cables.
My ISP left me with lots of surplus cable and I'm not positive that it's CAT6. I have lots of CAT5 cable from when I built the house back in 2000. I thought the CAT6 connectors might be better but didn't realize they might be trickier to do right.
When the 8 wires are inserted you do not want to have "wire float". Being the wire should only be a little smaller than the size of the hole it's sliding in. So get the proper connector for the cable you are using. Indoor and outdoor cable have different thickness of outer insulation and may require different connectors.
Also to meet the full speed that CAT6 allows you need to have only a tiny amount of untwisted cable in the connector and to me that's very difficult without a passthru connector.
