I got a Greddy EGT gauge from B16MIKE and he wasn't sure if it worked or not so he sent it to me before he got payment so I could test it. Anyways I don't have a manual for it and need to know where the wires go.
Temp goes from 400-1200 degrees Celcius.
On the back there is a number that says EX 50180
There are five wires coming out of it, two for the Probe, I know which ones they are, but there are 3 others that I'm not sure on, one is black (I'm guessing ground) one is white and the other is red.
Does anyone have a gauge like this and know where these wires go?
Any help is appreciated.

Thanks

black is ground red is switch so it could be in use while in daylight with no light and white is a switch for the actual backlighting

 

Ok so basically I just run power to the red one and put a switch on the white one so I can turn the lights on and off?

 

yeah power to the red on and splice your interoir lights and hook that wire to the white

 

Great thanks alot man!!
