I'm not sure. According to the manual, there is supposed to be a speed and brake assembly. All I have is the brake handle portion (not pictured). The rubber handle doesn't look like an original compared to the half-way decent photos I could find. It sports a "DeGrip" name on one side and the other states to keep the "^ Flat side up ^" and "Made in U.S.A". The grip texture is nothing like I remember in the Arcades. The other is a plastic handle, but I'm not sure if it's original or not. Doubt it, looks like it was hammered on. The
MAWS entry shows the handles that I remember, but it shows an additional red button(?) along with the original yellow.
Apparently, these controsl took a lot of beating in the arcades?
The harness was probably hacked. In the 2nd photo, There are two red molar connectors, the one on the left still has its mate which was hacked off whaterver it was connected to. The ground(?) from it has been shorted to a lead in the right molar connector. Probably a redneck way of setting the throttle to max and let the gamer slow the bike with the brake... lame

The other molar connector was attached to the start button, with some crappy soldering work. Easy enough fix.
There are also two stray wires with no molar connector, I think these are for the hacked off light bulbs. I figure on replacing them with some fabricated mounts with super bright LEDs.
It's just so hard visualizing what the completed assembly is supposed to look like when all I have are bits and pieces of diagrams and the like.
