Greddy EGT gauge

[Reese92tsi]

For some reason my Greddy EGT gauge wont work. The backlight works but the gauge itself doesn't work plus it didn't come with any instructions. This is how I wired it up Red=12v w/ignition on, black=grnd, Orange=wired in with dash lights for backlight, White=grnd. Am I doing something wrong?

Can you post a picture of the wiring?

Did you get the egt peak and hold electronic one or the regular one...

The regualar one has a faq on it from Greddy WEbsite the electronic one doesn't have one there and I need it if anyone knows where to find it.

It turns out that Orange is 12v constant power, Red is switched power, white is for the backlight and black=grnd. The darn instructions were missing
