Note:  The connectors on this cable are .110 in size, which means they are compatible with the pushbuttons that are the same size.   The American style pushbuttons (in our store, we carry the IL - Industrias Lorenzo brand) are .187 so this cable is not compatible with those.

Simplicity + Plug and Play

One of our main goals is to make your modding projects not only simpler, but also faster—giving you more time to focus on the more intensive parts of your build.

The Brook UFB was already a huge step in lowering the learning curve for stick modding, bringing multi-system compatibility to stock arcade controllers. Traditionally, connectivity meant taking each wire and connecting them one-by-one to the terminal block. Not difficult—but definitely time-consuming.

This harness changes all that.

• 20-Pin Connector: One side plugs directly into the Brook UFB. That’s it. No more individual wires to the terminal block.

• Branching Harnesses:

  • Two 4-button harnesses for pushbuttons

  • A 3-pin connector for control functions

  • A 5-pin JST connector (compatible with Sanwa Denshi JLF, Hori Hayabusa, and Seimitsu joysticks)

The result? A super clean, plug-and-play setup. For fresh mods, this cable saves 15–30 minutes of wiring time compared to making one from scratch—depending on your experience level.

Custom Made for Arcade Cabinet Builds (Twice the length of the standard 20-pin harness) 

For years, walk-in customers asked us about longer 20-pin harnesses. At first we thought: “Why would you even need that?”

But with the rise of Arcade1Up and other in-home arcade cabinets, PCB placement became a different challenge compared to a standard arcade stick. Builders wanted more flexibility in where to mount their PCBs, but stock 20-pin harnesses limited their options—forcing many to create custom cables themselves.

This harness solves that problem by providing the length and flexibility needed for modern cabinet projects—without the hassle of DIY wiring.
