How to make rj45-wiring connections
In many cases of residential rj45-wiring for networks, you will only put the rj45 end on to plug into the distribution panel. The other end in the bedroom, office, or wherever, will have a keystone jack, which is similar to a modular phone jack.
If you are just adding a home network to an existing home, you may want to consider using a wireless router for Internet. That’s not as secure, but it’s much easier than drilling holes into everything.
There is a loose standard as to the exact order of the wires into keystone jacks, so just be sure to put the wires in the same order on both ends of the circuit.
The keystone is actually color-coded and you just lay the coordinating colored wires in place and use a punch down tool to secure the wires.
Some keystone jacks have a cover that fits over the back of the port and snaps in place acting like a punchdown tool.
The keystone jacks fit into an electric box just like outlets and phone jacks do.
Once the Cat5 lines are terminated on both ends, they need to be tested with a line testers. These will test all the wires in the Cat5 cable to make sure each has a good connection. The testers are really inexpensive and worth the cost.

My newsletter keeps you up to date on home construction and design ideas.
I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.
Benny Luis Lopez,
I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
