Equinox Valve Stems??

I am ordering a TireMinder pressure monitoring system for my MH and Equinox (toad) There are two types of sensors/transmitters. One is for brass or stainless stems and the other type is for aluminum stems. The valve stems on my 2010 Equinox look like hard rubber.

What type of sensors/transmitters will I need to get?

Edit: I figured this out - this thread can be deleted.
