Hi thanks for all that info. It looks like you need a new console.
They dont make anything you could easily adapt .
It would actually require a lot of interface circuits etc to do that.
Unfortunately the best supplier is in the US and I dont even see one local to you ;(
The best place to get a new console is: https://www.treadmilldoctor.com
I would call them on this part:
TOLL FREE 8am - 5pm Mon - Fri CST
In any case, I will stick with you until this is complete.
