the 2 heavy green wires are earth ground
the other wires are dc+ red
                            dc - black
the other 4 wires are your x and y axis outputs
on my happ track ball new style (open frame) using the red sensor boards
as follows
purple  @ blue =1 axis
green  @ yellow = 1 axis

Welcome aboard, Ronfedele.   ;D

just bought an ipac 2 my board has a happ trackball no idea of model it has 10 wires coming off it 2 bundles of 4  and 2 separate heavier gauge green wires     what is my pinout to molex connector for ipac   and do i need to run separate power
The two heavier gauge wires are frame ground.
- They bleed off the static charge generated by the rolling trackball.
- Connect them to ground like the case of the power supply.

You don't need a separate power connection.

The two bundles of 4 wires contain:
- 5v (red)
- Ground (black)
- Two data lines X1/X2 or Y1/Y2 (purple/blue or yellow/green)

The 8 wires go to the 0.1" (Dupont) pins labeled "trackball". (left center)



If your trackball has an arcade-style Molex (white 6-pin below) harness instead of one with 0.1" (Dupont) connectors, GGG carries a Trackball Cable for Opti-Wiz™ "No-Solder" that replaces the molex harness.



The replacement cable plugs into the optical "red boards" on the trackball and has Dupont pins on the other end.
(click image for full-size)


The image above shows an Opti-Wiz, but the trackball cable will work the same way for your I-Pac2 -- just lift the tiny lever and pull the female Dupont ground pin out of the 5v/ground Dupont housing since 5v and ground aren't on adjacent pins.

Troubleshooting:
If an axis is reversed, swap the data lines for that axis.
i.e.  If moving the trackball right moves the mouse cursor left, swap the X-axis data lines (purple and blue wires)

Can the Happ trackball used as a mouse with the ipac2?

Yes, a Happ arcade-style trackball (the kind with a 6-pin Molex, not the kind with the Happ PS/2 or USB encoder :puke ) + I-Pac works exactly like a mouse.

The I-Pac firmware shows up as a USB HID Mouse device so it will work with any system that has a generic USB mouse driver.

Of course, this assumes that you have a 2015 or newer I-Pac with the trackball optical input pins. (pictured above)
