 Sega's Astro City, Blast City, Net City and Naomi Universal cabinets use a connector system that's common between them.  More or less.  They use the AMP/TE Universal Power family of connectors.
-==== Controllers ====
+On all connectors, there is a key that indicates the location of pin #1.  For this reason, no attempt has been made below to indicate //plug// or //socket// because it doesn't matter.  Pin 1 is always pin 1.
-{{ :arcade:amp-4p.svg |}}
+=== Gender, Pins, Tabs & Sockets ===
+Somewhat confusingly, the shape of the plug determines whether it is a //plug// or a //socket//.  Normally the smallest element - the pins inside the plug - determine this.  So, when you have the socket mounted to the cabinet bracket, it has tab pins, and the plug coming from the control panel has socket pins.
+For all of these connectors, the part codes are listed.  The pins come in two gauges, typically the large gauge (lower numbers) are used for power, the smaller gauge (higher numbers) are used for everything else.  The last number indicates the alloy type, but for our purposes this isn't important.  The cheaper parts have been listed here.

+**ProTip:** A very expensive special tool is needed when pins are removed from these connectors.  You can file down a small screwdriver (a tiny allen tip is a good start) or use a spare pin instead.  The pins are the perfect width and length to reach the clasp inside the connector housing.
+The last digit of every **plug** or **socket** is the //colour//.  Most of these colours are no longer available, but maybe you'll get lucky.  The colours are:
+^  Digit  ^  Colour  ^
+|  1 | Natural  |
+|  2 | Red  |
+|  4 | Yellow  |
+|  6 | Blue  |
+|  9 | Black  |
+===== Control Input =====
+==== Primary Controls ====
+The 12-pin connector carries most of the player's necessary control inputs.  Start, stick and buttons 1-3.  On Net City and Naomi cabinets, it carries buttons 1-5.
+{{:arcade:amp-12.png?150 | }}
+^ Pin ^ Function ^ Pin ^ Function ^ Pin ^ Function ^
+|  1  | Start |  5  | Down |  9  | Button 4  |
+|  2  | Right |  6  | Button 1 |  10  | Button 5 |
+|  3  | Left |  7  | Button 2 |  11  | +5V |
+|  4  | Up |  8  | Button 3 |  12  | Ground |
+Buttons 4-6 (4-7 for Net City & Naomi) can be found on the extra buttons connector (aka kick harness).
+===== Extra Buttons =====
+The extra button connector changed when the Net City, New Net City and Naomi Universal cabinets came out.  The //ground// pin was moved from 4 to 5, and //button 7// was added.  So there are two pinouts for this connector.
+Note however that it seems the connector is fully populated and runs straight through, even on a New Astro City.  Based on the wire colours, 14 is supposed to be +5V and 15 is Ground.  However the //intent// of each wire isn't relevant: all 10 pins run straight through from end to end, so as long as your panel and receiving device expect the same signal in the same position.
+The upshot is, at least on the New Astro City and the Naomi Universal Cabinet, you'll get the same results.  You can safely ignore the pinout of the connectors and worry about what's on either end.

+===== Audio =====
+Sega used the same connector with two different pinouts, depending on the audio function.  The signals running into the stereo amplifier (if there is one) were different than the stereo speaker outputs from the amp or power supply.  While all of these cabs had stereo speakers, many had only mono sound.

+===== Coin Counter =====
+For some reason the coin counter must be connected in order for the coin slot/coin input to work, because the ground line to the coin slot goes through the counter.  Seems like a security issue, making it harder to ring in credits without triggering the counter as well?  In any case, if you unplug the counter, you can't trigger a coin input.
