I hope you have better luck with the Glowshift gauges than I had. Out of five gauges I have only two still working, both mechanical.
Fuel pressure: two different sensors went bad, now the gauge lights are not always working.
Tranny temp: the needle started violently banging from stop to stop. I disconnected it from the sensor wondering if the problem might be in the sensor, like the fuel pressure sensor. The needle continued the violent banging stop to stop. It finally died.
Coolant temp: started reading way off temps, then started banging stop to stop.
I gave up on these gauges since only the mechanical gauges, EGT and boost, still work. Wasted money.
