I tried to finish mine off today, but immediately managed to pull the oil temp sensor wiring apart from the clip, so I can no longer plug the wiring from the sensor into the back of the gauge. So I thought I will worry about it later.

Powered up all three gauges, and now the boost seems to be out. I previously had the boost gauge installed by itself and it showed roughly 1.2 Bar which seemed accurate, I have not changed the wiring for the boost gauge, except linking the power to the other two gauges, and now the boost gauge is only reading 0.6 Bar.

So weird I am now completely stumped. I have a oil temp gauge that reads 0 all the time, a voltage gauge that seems to be fine and a boost gauge which reads completely off.
