PFC 737 yoke rewire

I recently replaced the usb board on a PFC USB Jetliner Yoke owing to faulty axis readings. (The previous owner sold it to me "as new" but it has had problems from day one). Anyway, the old usb board was no longer available and so i ordered the new usb board with the new wiring instructions from PFC.
The axis is now fixed but the rocker switches for the trim also needed rewiring.

After re-wiring as per the instructions i am only getting readings when the switches are pressed down. I have e-mailed PFC but just wondering if anyone has any suggestions in the meantime.

Thanks all
Best wishes for the new year
