Katoom,
The TST TPMS is very easy to install.
You need to have metal valve stems on the tires. That may be the only hassle.
The sensors screw onto the vavle stem and transmit (wirelessly) to the monitor in the cab.
Since each sensor transmit a unique code, the monitor needs to know which sensor is on which tire.
That is easy, but takes some time....you press a sequence of buttons on the monitor, then hold the monitor next to the sensor until the monitor recognizes it. Maybe 1-2 minutes per tire.
I hope that helps.
Cheers,
