This is the smallest
TPMS display available from CAREUD (the only brand I've found that works reliably), but it only displays pressure OR temperature, and temperature only in Celsius. So I may switch to the larger display that I have in my other trucks. It's powered by the same instrument circuit (R/Y) that I used for the RV mirror. I'll probably also use that splice for the in-dash key-switched USB power supply for the dash cam.
