That was the 104E e-unit models.  In that case you had a DCDR and the 104E was the conventional control of the DCDR.  You replaced it with the R2LC.  If you read the TMCC Upgrade instruction with the kit, that is what you did UNLESS you had the early upgradeable Hudsons and Pacifics.  In that case you had no DCDR.  Instead you had the 103E unit and an open spot on the Mother board to ADD the R2LC.  Notice one board has Motor Transistors and one does not.
