This is the first JD tractor harness (on the right) and the convenience plug (not even sure what that's for) on the left.

The planter end of this one is labeled "Tractor". Not sure what it's for either but I think probably the compressor and AMS stuff?

Next is the second JD tractor harness. By this time we were running out of room on the back of the tractor so we had to zip tie it to the top link on the 3-point.

Finally the 7-pin connector. I don't know if you can see it or not in this picture but we ran 10 gauge wire to it because John Deere told us that all Case tractors had problems with the electronics on Deere planters and they thought it was because the wire running to the 7 pin connector on the Case was too small.
