Небольшая инструкция по данной системе -70, скрутить можно, но нужен специнструмент (Sensors cannot be stolen -special key required for removal), компактная и удобная система, пользуюсь такой, смотреть особо и не нужно, в случае чего дается световой и звуковой сигнал.
DIY Steelmate Automotive Tyre Pressure Monitoring System (TPMS)
The system comes with 4 screw on sensors and a cigarette plug display which shows in real time the current tyre pressures of all 4 tyres in PSI format in a circular scrolling motion. The cigarette plug display also has audible and visual warnings when a tyre pressure drops below or raises above the recommended level. All sensors come pre paired to the correct wheel position and are labelled for easy installation, simply screw each sensor onto the vehicle valve stem then lock in place with the provided locknut and tool.
