TMCC Wiring schematic

The green wire doesn't go anywhere, it's not used in this installation.

The blue wire should be going to serial data, but it goes to a wire nut, that doesn't look right!  Those gray wires in the wire nut sure don't look like serial data to me!

Obviously the two motor wires from the CC-M should go to the tether, at to what pins, you'll have to use your meter to figure that out.

I can't see any of the other wires well enough to offer useful solutions.

Thanks John, I hope the previous installation can be undone and there was no damage because it was goofed up.  Time will tell....

Hard to tell, you really have to see where all the wires go and make sure they're in the right places.
