 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.
+  * **Tabs**
+    * (AWG 22-26): 175149-2
+    * (AWG 16-20): 175150-2
+  * **Sockets**
+    * (AWG 22-26): 175151-2
+    * (AWG 16-20): 175152-2
+===== 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.

+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.
