 === 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.
+⚠️ The TE series plastic //plug// uses a //socket// inner connector, and vice versa.  This nomenclature is sort of backwards to what you might expect.  The arrows in the table below indicate the proper connectors for both types.
 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.

+For the **power supply** sockets, the second part number indicates the panel-mount part.  The first number is for cables.
+**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.

 ===== 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.
+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 on pin 4.  And in order to prevent confusion, the connector was changed from 10 to 15 pins.  The third row is unused.
+Note that, at least on a **New Astro City**, it seems the connector is fully populated in the cabinet, and runs straight through from panel to board.  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.

-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.
+Sega used the same connector with two different pinouts, depending on the audio function.  It seems that most Astro and Blast City cabinets used the same pinout, some Astro City cabs had stereo amps that used an alternate arrangement.  Both are shown, but for your own sanity, you should check the wiring in your cab.

+===== 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.
