Where did "wired" come from?
I am not a coffee drinker, but I just drank some coffee. I said to my Hispanic friend, "I am WIRED!" and had to explain what the slang term means. However now that I think about it, that's an awfully strange term for "very very awake." Where did the word come from?
Solution 1:
If you've ever had an electric shock, you're well aware of the jolting effects of a live wire.
It didn't take too long for the term live wire to enter the vernacular:
Probably everybody likes to be known as a "live wire." The First National Bank, of Ashland, Ala. thinks so for they recently used an advertisement which read as follows: "Every live wire has a bank account. Are you a live wire?" (The Bankers magazine, 1921).
If, however, you accuse yourself of being a live wire and capable of acting without the sound of a gong or the beck of a boss (from a 1922 ad)
More recently, from the realm of music:
Don't touch me, I'm a real live wire (Talking Heads, Psycho Killer)
I'm guessing that wired evolved from the term live wire, which connotes being energetic, full of verve, and ready to go.
Solution 2:
The Online Etymology Dictionary says:
Wired (adj.) "nervous, jittery" is from 1970s.
Google Books tells us it's in print in the early 1970s and late 1960s as US and Canadian street slang, and appears to originate from Canada in the 1950s, if not earlier.
The earlier uses seem to mean hooked or addicted (for example to heroin), possibly from a suggestion of being connected to, wired to. This would follow some other earlier uses such "wired for electricity", "wired for aircon" and "wired for sound".
(Other earlier uses of wired are to have messaged someone by telegraph or other means ("I wired the Chicago office"), and it's sometimes used in discussions of how someone's "brain is wired up". It's not clear if these influenced the drug slang term.)
Later uses seem to mean being high, or on a buzz (for example on meths). Around the 1970s, this then became current when talking of legal drugs (for example prescription stimulant drugs, "uppers"), and then quite naturally was soon used for another legal stimulant drug, caffeine, which of course is found in coffee.
1971
Peter Marin and Allan Y. Cohen give an etymology in their 1971 Understanding drug use: an adult's guide to drugs and the young:
In some ways they are the most dangerous of the popular drugs. Known as "crystal" and "speed," they generally create an electric sense of well-being and vitality — a condition the young call being "up" or "wired".
Likewise, John H. Frykman's 1971 A new connection: an approach to persons involved in compulsive drug use:
amped "Wired" on crystal (methamphetamine); stems from the original Methedrine ampules, small glass vials in which pharmaceutical methamphetamine was sold

1970
It is used in a 1970 snippet of The Accountants Digest, where it describes drug use:
This makes them too "wired" to work, so they take a tranquilizer to relax them. At lunch they have three to four martinis which servce to put them "down." After lunch they take two or three Dexadrines to wake them up. This causes them to become too high, too "wired," so they need more tranquilizers. Finally, they take four barbiturates to put them to sleep.

Keeny saw that Gato, who used hard drugs, was wired up. He was chuckling as he jingled some coins in his hand; his bearing was the boundlessly optimistic air of one high on heroin.

(Hathi Trust has this journal for searching but full view is unavailable for copyright reasons. Searching different entries, "wired" is found on page 24 of "The Social worker. Travailleur social. v.20-23 (Oct 1951-July 19." and page 24 of "The Social worker. Travailleur social. v.22-23 1953-1955." but not in "The Social worker. Travailleur social. v.20-21 1951-1953.", so a 1953-1955 use looks promising.)
