@clytle374 I don't think interference is the issue. If you're talking about connecting a thermocouple as you would a thermistor or PT100, ie connecting it to the TEMP pins (P5) under the board, then running the thermocouple wires with the wiring loom, connecting them to INPUT2, I think this will cause problems. You've got the metal of the pin, then the copper of the PCB, then more metal of the pin. The way a thermocouple works, I think it will effect the reading.
If you need a high temperature sensor to use with the Smart Effector that keeps the wiring neat, I'd suggest using a PT100.
