First, it doesn't matter which red wire is which. As long as the two reds are soldered to the two red terminals (#2 & #3 on the connector I believe), and the white is soldered to terminal #1. It does matter, however, that all the wires have the same resistance (all same length). Also, if you look really closely on the connectors, there are embossed numbers next to each pin. The end of the cable that came with the RTD has a "T" embossed on the connector (not numbers); that end has
to connect to the RTD probe. It will connect to the panel mount QD, but the PID won't work if connected that way.
EDIT: not sure if you've seen this, but my post here
shows how I made my RTD connectivity.
