Hello my name is CLTOMIC JD 870 starting problem

[cltomic1]

I have an old version of the cranking system that I have been using to check the starting system. But my tractor is a 1995, and has a B in the serial number instead of an A, so I'm wondering if anyone has knowledge of where I might get a new version of the cranking diagram? Some of the wires on my TDCM are different than what my old version talks about.
