I received the jd2912 relays. what email address do i email?

You can contact son of wil through Amazon.

so in the picture the top red wire that is 87 goes to the motor to turn it on but it shows in the picture red turns to black and it is ground?

The red wire goes to the device that you want to turn on and the black to that Device

what gauge wire on battery terminals

I used a 14 gauge wire to the battery

I have a positively grounded (+ ground) system. The relay coil should still operate correct?

If you are stating the chassis is battery plus, then it should work, but would need to cycle your negative signals to control coils. John Deere 60 tractors have a positive chassis methodology, so might need to investigate how they operate to verify implementation.
