Welcome aboard, Ronfedele.
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.

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)
