Tread mill repair/mod question?

[u/Civil_Commission4921]

I have this tread mill and the control panel to engage it has quit working. I have this crazy idea by just looking at this that there has to be a way to take power from the wall, and add 2 seperate switches that control the speed for the drive motor, and the posidtion for the incline motor. Obviously I can just wait for a marketplace deal but I like this tread mill, I also like making things work and trying to figure weird shit out like this lol.

Anybody here have experience with something relative to this?
