Help TPMS driving me nuts.

Hi All,
New here, just got my first Tundra after many Tacomas. So my 2019 Tundra Limited had what I assume was a factory remote starter as it worked with my Toyota key FOB, this is a key start truck not a push button. So I had the Toyota unit removed and a Compustar remote start installed in its place at a factory authorized Compustar dealer. All works perfect with the exception that none of the TPSM sensors are reading know so the TPMS light on the dash is always is always on, very annoying. I tried the reset on the dash. I am currently in debate with the installed if there needed to be a splice for the TPMS. Does anyone know the answer??

Thank you in advance.
