I have put together a Track and Field trackball control panel, but it was bare when I got it.

I got 2 Wico 2.25in Trackballs.
I bought the Stern adapter board for the trackballs over Ebay, and replaced some components on it but I'm still not sure if it's working.

I thought I wired it up correctly, but would like to see a pic or hear from someone with a working Track and Field trackball.

In the Stern manual, it states Pin3 is TKBL1 on the control panel connector, and Pin6 is TKBL2. These go to the adapter board in locations pin1 and pin 7 respectively. Then as you can see, Pins 3 and 4 are TBR and TBL. I am assuming that is the right player trackball (run) and left player trackball (run), however I don't know which pin on the track ball harness to hook it up to. I want to spin the trackball to the right to run. So I have it hooked up to the purple wire of the trackball, and that is going to pin 4 (TBL) on the adapter board (this is the left trackball). However the trackball does not make the player run at all. Do I need to hook up both the horizontal wires to the single pin 4? I just did the one spinning right.

I've never played the trackball version, if someone could also tell me if you can spin the trackball both ways?
