Hy Coyote, I wish I new more about computers, that picture is still too small for me to see much. Have you traced the line connected to that device, I am assuming that the primary system is operating the rear brakes, so this device is probably connected to the front brake system. There aren't any wires connected to this device are there? As to your trans. question, I believe the fill plug is on the left side just in front of the pto opening. Is this truck a tractor or a single unit?
