Greddy 52mm EGT Gauge Needle stuck at 1200 Celcius...
yes, I have searched and haven't found much on this. I just installed the Greddy EGT Gauge in my RS and when I turn the car off, the needle goes past the 12 mark on the right.
When I turn the car back on, after about 4 minutes, the gauge starts functioning again. Very weird. I don't think I have the wires connected wrong: 12v Constant: #4 Fuse Box (Cigarrete Lighter) 12v Switched: #? Washer Illumination: #? Illumination Location on the Fuse Box Ground: Bolt that holds the brake pedal assembly to the firewall of the car. I unplugged it and the gauge needle goes back to the bottom as normal soooo I don't know. Any ideas? Perhaps I do have the 12v Switched or one of them screwed up... Any help would be greatly appreciated. Thanks, Kevin

12v Switched may be ok in that position. I used the cigarette lighter wire. Illumination has nothing to do with your problem. Ground seems to be ok. |

I'll just go back and use a damn relay like had originally planned to power my 4 gauges and other things that need 12v constant and 12v switched....
I just wanted to use this as a temp solution while i get the other gauges... |

The cig wire for power is likely your problem. I know in the 02+ it is not constant voltage with the key off so when you kill power the gauge stops functioning.
Sounds like you are headed the right way with the relay though. |
