Hello,
Sorry to bring this thread back from the dead, but I'm working on a friend's Thermador, built by KitchenAid, SxS with a freezing fill tube. I installed part number AP5330657, but have nowhere to install the wires. A later version of this unit had a plug, into which the wires will plug, but the unit I'm working on does not.
So, I have a couple questions. First, is there a plug up top that I'm missing? There is one, but the connector is different and it's not energized. The wire colors are BK-W and W-O. Second, if there is no harness, can I splice into the main L1/N that are leaving out of the power switch, assuming that the heater is always energized.

Thanks,
Kris

Thanks, Jerry.

When I got into work this morning, I was able to look up the wire diagram (attached) and found that the 2-pin harness that's up there is the fill tube heater harness, but with a different connection.

I'm going to go back, cut the connectors and wire nut the harnesses together.

The model number is KBUDT4850A/01

Thanks again..

Kris
