Used this mini-temp gauge and sensor to replace my idiot light sensor when it died on my Triumph. The sensor is a die cast metal and not brass like my stock part. The mini display fit under my ignitition key using velcro that came with unit. Unit works well, easy to install. I haven't wired the back light. Great overall value, average quality rating only for the non-brass sensor. My bike had 10mm-1.0 sensor thread and this unit came with a 1/8MNPT thread. I took a 10mm nut (close to 1/8 in size) that matched old sensor and ran it over new sensor to swage the threads and not damage my engine block. Also put gasket sealant on threads to make sure no leak.
