Besides the error code function, does anyone know if the ecm/es control unit from an 03-06 will work on a 00-02.5? I usually keep a new 00-02.5 control unit in stock, but have had this 03-06 unit on the shelf for a while and need to move it. The 02 rancher 350 not shifting, have verified it's the control unit, but don't want to fry a new box if it is known not to be compatible lol. They "look" the same, just plugs different color.
