    Do you have to have the ratio adapter or can you go right to trans?

      @@dougstrucksnstuff you can plug the ratio adapter inline anywhere between two points, except it can’t go right on the back of the speedometer. Between any other cables or right into the trans is fine. Or you could use a direct cable with no adapter and pull the gears out of the trans for the speedometer takeoff and change them, but that’s a little more involved.
