Field guidesfor the work
The things people actually search for at eleven at night, answered properly: which colour goes on which pin, what a bridging clip does, how much twist you are allowed to lose, and what a finished switch configuration should contain. Interactive where a diagram beats a paragraph.

Copper,
pin by pin
Termination work, with the colour codes rendered rather than described. Every diagram is interactive because the question is always 'which one goes here', and a picture you can flip answers it faster than a table you have to read twice.

RJ45 Wiring: T568A and T568B
Both colour codes, pin by pin, side by side.
The two eight-position colour codes in full, with an interactive pinout you can flip between. Shows which pins actually move between A and B, which pairs carry data on 100 megabit versus gigabit, and how a crossover cable is built — plus why you almost certainly do not need one.
Who reaches for itAnyone terminating a plug or jack and wanting to be certain which colour goes where before they crimp.

RJ11 Wiring and Phone Pinouts
Six positions, three lines, two colour systems.
The six-position telephone pinout, shown for one, two, and three lines. Covers both the old four-colour quad station wire and the twisted-pair equivalent used in modern work, explains tip and ring, and shows why lines number outward from the centre pair.
Who reaches for itAnyone terminating a phone jack, tracing a line in an older building, or working out why line 2 is dead.

Keystone Jack Termination
Strip, seat, punch, snap — without failing the certification.
How to terminate a keystone jack so it certifies: how much jacket to strip, how much twist you are allowed to lose, which way the punchdown blade faces, and the handful of mistakes that account for nearly every failed test.
Who reaches for itAnyone landing outlets or loading a patch panel and wanting the run to certify first time.

66 Block Wiring
Fifty rows, four columns, and where the bridging clips go.
How a 66 block is actually organised: which columns are bridged to which, where the incoming pairs land, what the bridging clips do, and how the 25-pair colour code maps onto the rows. Includes an interactive block you can step through pair by pair.
Who reaches for itAnyone working analogue telephone distribution in an older building, or tracing what a previous decade left behind.

110 Block Wiring
Lay the pairs in, press the connecting block on.
The two-stage termination that confuses people the first time: conductors lay into the base in colour order, then a four- or five-pair connecting block presses over them and seats every contact at once. Covers lay-in order, connecting block sizes, and how the cross-connect is made on top.
Who reaches for itAnyone terminating horizontal cable onto a wall field rather than a patch panel.

Configuration,
in the order you do it
What a switch configuration should contain when you hand it over — with your own VLAN numbers substituted in, and a note on each section explaining what breaks when it is missing.
The words,
and what they mean
Definitions written for someone standing in front of the thing, not someone reading about it. Searchable and cross-linked.
Every one of these is something we have had to explain on site, usually to somebody competent who had simply never been shown.
There is a lot of wiring information on the internet and a great deal of it is wrong, contradictory, or a nine-minute video of somebody’s hands. So these say the thing plainly, show the colours rather than naming them, and are specific about where the standard ends and field practice begins — because those are not the same, and pretending otherwise is how people end up defending a decision they cannot source.
- No account, no email gate, no video.
- Nothing you enter is stored or transmitted.
- Colour is never the only way information is carried — every swatch is named in text.
- Where a standard specifies a number, it is cited as a standard. Where it is field practice, it says so.
- Guides, not engineering sign-off. On a job with a certification requirement, certify it.
We pull the cable
as well as explain it
If you are reading a termination guide because a building full of it needs doing, that is the work we do. Estimates are free and the conversation costs nothing.
