The kit includes one Motorola 2.5 Bar Map sensor,detachable connector and 12" of colored wire with online instructions to hook it into your stock MAP wiring. Upgrading from a stock Honda/Acura Map sensor that can only read ~10 psi of boost will allow you to run up to ~21.75 psi of boost as well as set a boost cut in your engine management. This safety feature has saved many motors from overboosting due to many random factors/problems that occur on Turbo Charged vehicles. This sensor is extremely linear which makes for ease of tuning.
