John Deere Smart Connect. I will be installing the smart connect on my John Deere 5075E. This is how I installed this and you will see the manual did not match my machine. I had to modify the install.
Parts used:
BSJ10674
Here is a link to the two kits. You will have to verify which kit is correct for your tractor, there are others besides these two.

I believe the correct kit would be the BSJ10589 kit for my tractor. I was able to make this work and not have to wait for a different kit.
