Mimic Mod - Installation Instructions
Mimic Mod Installation Guide
*Troubleshooting tips at bottom of instructions.
New All in One Unit:

Step 1: Prepare the Machine
- ☐ 1. Power down the pinball machine.
- ☐ 2. Remove the balls from the machine.
Step 2: Add Power to the Backbox
- ☐ 1. Open the backbox.
- ☐ 2. Take the two included power cables:
- ☐ - Plug the small black and gray 3-pin cable into CN6 (gray side down).
- ☐ - Plug the Molex connector end into the main power cord
- ☐ 3. Feed the connected power cord down through the backbox into the cabinet.
- ☐ 4. Tuck it out of the way, then close the backbox.
Step 3: Remove Stock Hardware
- ☐ 1. Lift the playfield.
- ☐ 2. Fish the power cord to the front for accessory access.
- ☐ 3. Locate and unplug the spotlight and flasher Molex connectors.
- ☐ 4. Fish wires through to the plastic area to the top of the playfield
- ☐ 5. Remove existing plastics and retain all hardware (screws, risers).
Step 4: Assemble the Mimic Mod
- ☐ 1. Attach the flasher dome to the Mimic using top screws.
- ☐ 2. Mount the flasher lamp inside the dome using M3 nut/bolt.
- ☐ 3. Adjust and mount the spotlight with an added riser.
- ☐ 4. Secure the spotlight facing outward and route the cable in front of the mimic chest.
Step 5: Feed Cables Through the Playfield
- ☐ 1. Feed the following cables down through the playfield hole:
- ☐ - Servo cable
- ☐ - Spotlight and flasher cables
- ☐ 2. Feed one at a time to avoid tangling.
Step 6: Mount the Mimic Mod
- ☐ 1. Align main plastic mount with the two mounting points (front and rear standoffs).
- ☐ 2. Use original screws/nuts to secure.
- ☐ 3. Do not overtighten.
Step 7: Connect Accessories Under the Playfield
- ☐ 1. Connect from the pinball machine:
- ☐ - 3-prong (red/brown) = Mimic Flasher
- ☐ - 2-prong (orange/red) = Dome Flasher
- ☐ - Labeled 'spot lamp' = Spotlight
- ☐ 2. Use extenders if needed.
Step 8: Setup Electronics
- ☐ 1. Components: (NEW STYLE - White Box)
- ☐ - Electronic PCB
- ☐ Optocoupler Plug (blue/yellow)- connects to 2 prong plug coming from mimic
- ☐ 2. Connect power to Electronics
- ☐ 3. Secure electronics to wiring harness under playfield (use zip ties)
- or - Use double sided tape (on back of electronics) to attach to side of cabinet
- ☐ 1. Components: (OLD STYLE)
- ☐ - Arduino Nano: main controller
- ☐ - Buck Converter: voltage regulator
- ☐ - Optocoupler Module: reads flasher signal
- ☐ 2. Connect power to both Arduino and buck converter.
- ☐ 3. Secure near front of cabinet using plastic loop.
Step 9: Connect Control Cables (Old Style Only)
- ☐ 1. Plug optocoupler into remaining connector from mimic (yellow/blue)
- ☐ 2. Connect buck converter red/brown to servo (power and ground).
- ☐ 3. Connect orange signal wire from Arduino to servo.
Step 10: Final Assembly & Test
- ☐ 1. Lower playfield onto rails.
- ☐ 2. Complete any remaining cable connections.
- ☐ 3. Power on the machine.
- ☐ - Red LED on Arduino = power
- ☐ - Blue LED on Buck Converter = power
- ☐ - Mimic should 'breathe' automatically every ~45 seconds.
Optional Testing & Diagnostics
- ☐ 1. Enter menu: Diagnostics > LED Test.
- ☐ 2. Use Volume - button to find 'Treasure Flasher'.
- ☐ 3. Mimic will chomp when the flasher triggers.
- ☐ - It has a cooldown to prevent excessive motion.
Troubleshooting
Troubleshooting - Message the shop if you get stuck, we’ll get you fixed up.
“Mimic makes a noise when idle” - this can mean the servo cannot reach its 0 point. Power off the mimic and adjust the metal wire hinge down a notch on the servo (it has several mounting holes).
“Mimic is not opening/closing properly” - check for obstruction on the mimic such as the spotlight cable or the internal flasher getting in the way of the chest lid closing.
“My mimic has a rich, smoky odor and is not working” - power off your pinball machine, look at the servo wiring, did you plug in the cords backwards? Message me and we’ll get you a replacement servo.
