the six wires you have coming off the optiwiz should take care of your trackball. I think the 5V posts are only if you have something else looking for 5 volts off usb.

That's very helpful. When I plug the OptiWiz in, it is recognized by Windows but the trackball doesn't do anything. Is it possible those 6 wires are just misordered? Or a driver issue?
PL1:
The connector with blue and purple is for the X-axis. Connect to pins A+B.
(Looks correct in the photo below.)
The connector with green and yellow is for the Y-axis. Connect to pins C+D.
Red and black are for 5v and ground respectively. Connect them to the pins you circled in this photo.
If left/right are backwards, reverse the blue and purple connections.
If up/down are backwards, reverse the green and yellow connections.

Scott, you rock!
That did the trick. Now the trackball acts like a mouse. Up/down, left/right.
(btw, it turned out yellow/green connected to A+B, and purple/blue to C+D)
Okay, now the issue is- when I run MAME, it doesn't recognize the trackball on Golden Tee. How do I get that to work??

Not sure if there's a difference between Ultimarc's list of Happ trackball wiring colors and GGG wiring colors. :dunno
Wouldn't be the first time those two disagreed on a topic. :lol
Maybe you installed the trackball turned 90 or 270 degrees. :duckhunt
Either way, glad it works for you. :cheers:

Launch gt3d (I assume this is the version you're talking about.) Tab for menu and go to the "input (this game)" menu:
Track X analog = Mouse X
Track Y analog = Mouse Y
If it is already set to that, but it still doesn't work:
1. Highlight Track X analog
2. Press Enter
3. Press Escape (clears input)
4. Press Enter
5. Move trackball side-to-side.
Repeat for Y-axis.
You may also need to adjust the settings in "Analog Controls" menu or return settings to the default with the Enter key.

DaOld Man:
If what pl1 suggests dont do it, in the mame.ini, make sure mouse=1
Edit: I would hook up the green ground wire from the trackball to a good ground. (Incoming AC line ground, or hook it to the PC power supply metal case.)
