Place Skins Game kit electronics assembly on flat, static-free work surface.
Remove electronics cover and set aside. Inspect electronics for any damage and ensure all connectors are
properly seated.
3. LOCATE ELECTRONICS  
Place new groundplane (with electronics assembly, but without hard drive or
groundplane cover) in cabinet in location of previous assembly. JAMMA edge connector header should face
same direction as previous connector header. Mark mounting holes and set electronics aside.

WIRE CABINET
CAUTION: ATTACH CONNECTORS PROPERLY.
 Be sure that printed circuit board
(PCB) connectors mate properly. If connectors do not slip on easily, do not force them. A
reversed connector may damage video game machine and void warranty. Connector
keys only allow a connector to fit one set of pins on a board.
CAUTION: OBSERVE GROUNDING.  
Be aware of ground wires in game. Ground wires
are usually green or green with a yellow stripe. Reuse any existing ground wires, and use
ground wires included in this kit.
1. JAMMA HARNESS  
When wiring JAMMA harness to the controls and the CPU Board Assembly, refer to
Cabinet Wiring Diagram in Wiring Chapter.
2. Attach component end of JAMMA harness to mate on CPU Board Assembly.
3. Attach free end of joystick adapter harness to its mate connector (P8) on the CPU Board Assembly.
4. Attach keypad harness to its mate connector (P26) on the CPU Board Assembly. Attach the other end of the
harness to the pigtail on the keypad assembly Do not force connectors. They are keyed to fit only one way.
5. Attach Player 4 (P4) and coin door connectors to CPU Board Assembly.
6. Double check your connections to ensure they are all firm and secure. Do not force connectors.
7. JOYSTICK HARNESS  
Attach free connector of joystick harness to its mate connector on the joystick adapter
harness H-23480. Connect one end of green/yellow wire to joystick mounting plate and other end to safety
ground.
8. BUTTONS  
Mate each of the five small buttons and start button to corresponding JAMMA wires.
9. Connect one end of an H-21672 ground braid to control panel and other end to safety ground on power supply.
10. Ensure each button is connected to ground through JAMMA harness black ground.
NOTICE:
 Hard disk drives are sensitive to static. W hen not in use, store drives in anti-static
bags. Do not drop or stack drives.
11. HARD DISK DRIVE  
Mount hard drive onto hard disk drive bracket. Note that end of bracket where holes are
spaced closer together is where ribbon cable connects.
12. Mount bracket onto studs on electronics assembly with included KEPS nuts.
13. Connect data ribbon cable and power cable to Hard Disk Drive.
14. Replace groundplane cover. Secure to groundplane using all but one of the enclosed nuts.

POWER UP AND TEST GAME
1. Plug line cord into AC power source and turn on power switch. LEDs in electronics cage should illuminate.
Using the 20-volt DC setting on a digital voltmeter, measure DC voltages at the power connector pins. Adjust
the +5V source if it is necessary. Voltage tolerances are ±.4 on +5V, ±½ V on +12Vhe game begins self
diagnostics. If no errors are found, Attract Mode begins. If problems occur, check wiring and refer to Trou-
bleshooting Chapter.
2. Unlock and open coin door. Press and hold TEST button to access Menu System. Use tests to verify operation
of monitor, hard drive, speakers, and all pushbuttons and joystick and keypad.
3. Exit the Select Test Menu to begin normal game operation. Open the coin door and press the SERVICE
CREDITS button to allow game play. Choose a player position and press the START button to begin. Listen to
the audio while playing the game. Note unexpected irregularities in sound (out of phase, no low frequencies,
etc.). Check the wiring harness for internal shorts. Refer to Wiring for jumper locations and recommended
settings, or Troubleshooting.
4. Close and lock coin door. Allow the system to operate for several hours before attempting any game changes.
5. Play several games to test operation of player panel buttons. Do they function? Do they operate consistently?
Does each control perform its designated operation? Game play and earnings depend on proper performance of
the VIEW, START and movement buttons. If any button does not operate properly, check connections against
the wiring diagram. Replace intermittent or otherwise faulty controls.
CAUTION: SEEK FCC APPROVAL.  Installation of this kit does not guarantee compliance
with FCC requirements. You are solely responsible, and Midway has no responsibility for FCC
compliance of installed kits. Don’t install an FCC compliance label on the product until the FCC
