GX71 Mark II GT - Digital Turbo Boost Gauge

This custom designed digital turbo boost gauge fits perfectly in the existing TEMS / ECT-S indicator window from the Kouki model GX71 Mark II Grande digital instrument cluster. I used the meter lens from the Zenki model Mark II GT to keep the existing TURBO indicator lamp in addition to my boost gauge. The factory Toyota boost pressure sender unit supplies the voltage signal to a bar display driver circuit, which outputs to the LED array.
