Hello everyone! I have a Ford New Holland 7740 and should do the clutch fill time calibration. In the manual I saw that, to run it, I need the Tool FNH-00874. I tried searching the internet but it's hard to find one now. So I ask you: does anyone know how it would be possible to build one? The tool, as I understand it, should be a normally open button that creates a bridge between two pins by connecting them to each other. If so, which pins should it connect? Thank you all!
