Adding wired motion sensors to Retrofit Alarm Kit

I have the Retrofit Kit and have wired the door sensors successfully. I have two wired motion sensors that I’m trying to wire now. I will be using the power from the legacy panel. There are 4 wires and when I removed the wires from the legacy panel and put them in the same sequence on the Retrofit, it wasn’t recignized. The wires were wired with one wire connected to AUX, one wire to the corresponding zone and two wires to a common. I did the same on the Retrofit to no avail. What am I doing wrong? Thanks for any insight.
