Upgraded Tennis Head Gripper for Diamond BT-M Stringing Machine

Hello everyone,

I have a Tennisman Diamond BT-M Stringing Machine, also known as Tourna 850 ES, with an old Puller. After watching the introductory video from Xpider about the new automatic Span Gripper, my mouth watered. I was able to buy a new tractor for about $400. But I don’t know where to replace it, with what connection to the motherboard. Can someone give me instructions? Or can someone who owns a similar tensioner take a picture to show me what the circuit board looks like inside the machine?

I thank you in advance
