unused holes with suitable filler material like quick-hardening wood putty. Sand wood smooth and 
remove dust.
4. Evenly cover entire cabinet with black paint and allow to dry before continuing.
5.SIDE DECALS
 Sponge soapy water over position of previous decal where you wish to locate decal 
on left side. See illustration below for location suggestion.
6. Remove an inch or two of Dark Legacy side decal backing paper to reveal some adhesive edge.
7. Line up exposed edge of decal and set down on cabinet.
8. Carefully remove a little more backing paper and place new decal onto of cabinet. Make location 
adjustments before removing backing paper from flames, as flames are more likely to tear than words.
9. Use dry sponge to flatten decal out as you place it down. Flatten out any air bubbles. Pop any persistent 
air bubbles with a knife or pin. If necessary, trim decal to fit cabinet.
10. Repeat previous five steps for right side decal.
11. MARQUEE  Remove existing marquee from cabinet. Check lamp and replace if cracked or if ends are 
darkened, even if it still works. Trim kit marquee to fit and install. Using previous shield as a guide, 
trim new attraction shield to size and deburr edges. Install new marquee attraction shield.
12. BEZEL Remove viewing glass and set in safe place. Clean CRT glass. Install black cardboard bezel in 
front of monitor. Apply instructions decals to top and bottom of bezel. Place Epilepsy Warning label 
on front of monitor bezel. Ensure decals and labels do not obstruct viewing area. Clean bezel and 
viewing glass before installing in cabinet.
13. CABINET  Unlock and remove rear door. Use vacuum cleaner to remove dirt or debris inside cabinet.

DECAL LOCATION
14. CONTROL PANEL  Locate and unlock control panel latches or fasteners. Free panel from operating 
position. Label harness wires before disconnecting from controls. Once wires are disconnected, 
remove control panel and set aside. Save mounting brackets and hardware for later reinstallation.
15. Some control panels have speakers or other components. Note wire polarity and function before dis-
connecting. Incorrectly phased speakers cause weak low frequencies or a thin, hollow sound quality.
INSTALL PLAYER CONTROLS
1. TEMPLATE  If control panel template is creased, flatten with books, newspapers, magazines, etc.
2. Remove buttons, joysticks, or other controls from control panel. Remove covering and artwork, hinges 
or mounting brackets.
3. Fill holes with suitable material (i.e., wood putty, glue, etc.). Let dry. Sand or file flat both sides of sur-
face. Should you choose to replace the control panel board, it must match the original panel in size and 
thickness, and include all fastening and grounding hardware.
4. Tape template on panel. Orient template to center controls. Cut and deburr holes. Remove template.

switch housing from underside of panel. Snap switch back on housing. Repeat for each button.
11. Rotate pushbuttons so switch terminals are oriented toward JAMMA harness. Tighten nuts firmly.
12. JOYSTICKS Insert joystick through hole from bottom of control panel. Align mounting holes in joy-
stick base with control panel holes and insert carriage bolts from top of control panel. Install nuts from 
bottom of control panel over bolts and tighten securely. Repeat for each joystick.
INSTALL ELECTRONICS
1. REMOVE OLD ELECTRONICS  Label, then carefully disconnect cables on each printed electronics 
board assembly in cabinet. Note orientation of JAMMA edge connector on CPU Board Assembly. 
Remove boards and store in anti-static bags. Leave JAMMA harness in cabinet so you can reuse it.
2. PREPARE ELECTRONICS  Place Gauntlet: Dark Legacy Universal Conversion 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 location of previous assembly. JAMMA edge connector header should face 
same direction as previous connector header. Mark mounting holes and set electronics aside.
4. MOUNT ELECTRONICS  Drill pilot holes where necessary and use hex-head screws to attach elec-
tronics to cabinet wall. Set DIP switches as needed (See Wiring Chapter).
WARNING. DISCONNECT POWER. To avoid electrical shock, turn off power switch and discon-
nect AC line cord before removing or replacing any component. After servicing components, be sure 
all ground wires are secure before restoring power.

nectors 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.
WARNING: OBSERVE GROUNDING. Be aware of ground wires in game. Ground wires are usu-
ally green or green with a yellow stripe. Reuse any existing ground wires, and use ground wires 
included in this kit.
NOTICE. Some older JAMMA connectors may require modification to work properly. Carefully 
observe Wiring Diagram, especially +12, +5, and -5 connections. Improper power supply connections 
can damage your video game machine.
CAUTION. Properly insulate any unused wires within the JAMMA wiring harness, especially red, 
yellow, orange, and black power wires. Secure any unused connectors away from game electronics.
