Suyi Electronics is a prominent manufacturer and supplier of the Jamma Arcade Game Machine Wiring Harness. Our wiring harness is engineered for reliable and long-lasting performance in arcade gaming machines. With over 15 years of experience in the industry, Suyi Electronics guarantees that our wiring harness is the ideal choice to enhance your gaming experience.
The SUYI Jamma Arcade Game Machine Wiring Harness is a multi-core loom engineered around the JAMMA (Japan Amusement Machine and Marketing Association) 56-pin edge-connector standard, so it mates with virtually every coin-operated cabinet and arcade PCB in commercial use today. Pre-terminated branches carry +5 V / +12 V / –5 V power, RGB video, mono audio, and full player-1 and player-2 input/output lines into a single drop-in assembly.
Built for sustained operation in busy arcade venues, the harness uses durable PVC tubing, abrasion-resistant conductor insulation, and a separately routed power / signal layout that suppresses electromagnetic interference. Custom pin counts (28 / 36 / 56 / 72), connector platings, and lead lengths are available on request, so OEM cabinet builders, retro restorers, and multi-game board makers can specify exactly what their build needs.

Key Features
JAMMA Multi-Pin Compatibility
Available in 28-pin, 36-pin, 56-pin (JAMMA standard), and 72-pin (extended) edge-connector formats, so the harness drops into every common coin-op cabinet and multi-game PCB.
Durable PVC Insulation
Abrasion-resistant PVC conductor insulation and an outer PVC tubing jacket stand up to the constant flexing, friction, and long operating hours inside a busy arcade cabinet.
Power & Signal Separation
Power rails (+5 V / +12 V / –5 V) are routed physically apart from low-level control and audio lines, preventing crosstalk and keeping gameplay signals clean.
EMI Resistance
Built-in electromagnetic-interference (EMI) resistance protects coin-counter pulses, joystick signals, and video sync from external noise generated by monitors and switching supplies.
Flame-Retardant Jacket
Flame-retardant jacket material contains any overheating event inside the cabinet, protecting the PCB, power supply, and operator under sustained high-load operating conditions.
Flexible Customisation
Pin count, lead length (0.5 m – 5 m), connector plating (gold / tin), jacket colour, and branding are all configurable — submit a drawing and we will quote within 24 hours.
Function & Working Principle
Functions
Delivers +5 V / +12 V / –5 V power from the switching supply to the game PCB through a keyed edge connector.
Routes 2-player control inputs (joystick directions, 6 action buttons, Start) plus coin-door and service-switch signals.
Carries RGB video and composite sync from the PCB to the cabinet display with proper ground reference.
Distributes mono speaker-level audio output to the cabinet's speaker pair.
Provides dedicated counter and lockout lines for one or two coin mechanisms.
Pre-wires screen, button, light, and payment peripherals via branch connectors for drop-in cabinet integration.
Working Principle
Edge-Connector Mating – The keyed 56-pin card-edge plug aligns with the PCB slot; the H/7 key slot prevents reversed insertion that could damage the board.
Power Distribution – Separate power branches route +5 V, +12 V, and –5 V from the switching supply to PCB power pins with terminal-fork terminations.
Control Signal Routing – Joystick and coin inputs are wired active-low to ground; the harness bundles them apart from power lines to suppress crosstalk.
Video & Audio Pass-Through – RGB video lines plus composite sync and the mono speaker pair are routed to the monitor connector and speaker terminals.
Peripheral Branch Connectors – Pre-terminated JST / Dupont / .187" (4.8 mm) quick-disconnect branches carry screen, button, light, and payment-device signals back to the PCB.

Our engineers have built wiring looms for coin-op, redemption, prize-vending, and claw-machine cabinets across more than 30 countries.
Quality Control Process
Every SUYI Jamma harness passes through five controlled stages — incoming material verification through to pre-shipment audit — to make sure each loom arrives ready to drop into a working cabinet.
Material Verification
RoHS / CE / UL docs checked
Wire Cutting & Stripping
Auto cut + strip to spec
Crimp & Assembly
IPC-A-620 crimp standards
100% Continuity Test
Every conductor verified
Pre-Shipment AQL Audit
AQL 0.65 sampling
Together these stages keep mean defect rates well below industry averages and give every SUYI Jamma harness the consistent plug-and-play feel that arcade operators expect.

Frequently Asked Questions (FAQ)
Will this SUYI Jamma harness work with my arcade cabinet or multi-game PCB?
Yes — our 56-pin harness follows the standard JAMMA (Japan Amusement Machine Manufacturers Marketing Association) pin-out, so it is drop-in compatible with virtually every coin-operated cabinet and standard JAMMA PCB on the market, including Pandora's Box, MAME-compatible multi-game kits, and original 1980s–1990s arcade boards. If your board uses a non-JAMMA connector (e.g. CPS-2 kick harness, Neo Geo MV-1C, Sega System 16), share your pin-out and we will either adapt the harness or quote a custom loom.
What is the difference between the 28-pin, 36-pin, 56-pin, and 72-pin options?
28-pin and 36-pin harnesses are used for compact DIY / Pandora-style cabinets and limited-feature boards. 56-pin is the original JAMMA standard, carrying +5 V, +12 V, –5 V, RGB video, mono audio, and full 2-player controls. The 72-pin version adds an extended edge connector (often paired with a kick harness) to support six-button fighting games and extra peripherals. Tell us your cabinet model or PCB type and we will recommend the right pin count.
Does the harness handle +5 V, +12 V, and –5 V power, and how are controls wired?
Yes. The 56-pin edge connector carries +5 V, +12 V, and –5 V from the switching power supply to the PCB on dedicated, physically apart conductors, with full ground returns to keep signal paths clean. All joystick, button, coin-switch, and service-switch lines are wired active-low — the input is triggered by grounding the pin, exactly as the JAMMA standard defines.
What wire gauge and insulation do you use, and why does it matter?
Our standard build uses 22 AWG tinned-copper conductors with durable, abrasion-resistant PVC insulation, rated for –20 °C to +60 °C operation inside a cabinet. Thinner 24 / 26 AWG looms from cheaper suppliers introduce resistance that drops the +5 V rail at the PCB — a common reason hidden in agones random resets. If you need a specific gauge, plating, or jacket colour for a regulatory or thermal reason, we can spec it in.
What is the minimum order quantity and can I get a sample first?
Sample orders start at 1 piece for evaluation — many DIY builders and arcade operators order a single harness to confirm fit before bulk purchasing. For OEM / ODM runs the typical MOQ is 100 pieces, but we adjust based on connector availability and lead time. Sample lead time is 5 – 10 working days, and sample cost can be refunded against your first bulk order.
How long is production lead time and how do you ship overseas?
Standard Jamma harnesses ship 7 – 15 working days after payment; customised builds typically 15 – 25 working days. We pack in poly-bag + 5-ply export carton with foam end-caps, and ship via DHL, FedEx, UPS, or sea freight depending on your timeline and budget. Air freight to North America, Europe, and Asia-Pacific usually takes 3 – 7 days door-to-door, with all customs paperwork handled by our export team.
Can you put our brand on the harness and packaging?
Yes — OEM branding is part of our standard service. Send us your logo (AI / PDF / PNG) and we will apply it via custom heat-shrink markings on branch connectors, printed connector boots, woven labels on the main trunk, or full retail packaging. Custom colour-coded conductors and bar-coded inner cartons are also available for distributors who re-sell SUYI harnesses under their own brand.
