The '''''Sega 2L12B Adapter''''', also known as '''''Sega Jamma/Jamma+ Adapter''''', is an adapter used to connect the Sega 2 lever 12 buttons panels to Jamma+ games. It is also possible to alter the wiring of this connector so it also act as a button remapper.

It connects between the various button looms from the panel and the panel connectors and reroutes the buttons 4 and 5 connected on the [[Sega Extra Button Loom]] connector to the regular player 1 and player 2 panel connector that are linked to the Jamma edge connector.

Using this connector allows fast and easy switching from a system using a Jamma and kick harness setup like [[CPS2]] to another system using a Jamma+ setup like [[SNK Neo Geo MVS]].

= Sega part number =
605-0028

= Pinout =
This is the unmodified pinout of the adapter. The color coding of the extra button connector may vary.
