George, you should be able to swap out the TMCC driver ( DCDR ) for the ERR Cruise M, ….you’ll have to add a wire for the serial data to control the M, but it’s not difficult at all,…..first things first would be to take a picture of the existing set up and let us have a looksie around with you,…you may have to add a serial buffer, depending on how much the data stream gets robbed by the M,….
