anybody have wiring diagram for a greddy egt warning gauge

[accident]

I got a used greddy egt peak/hold/warning gauge and it didn't come with the instructions. I would like to know what the 5 wires that go to the little white box are.
thanks, ed

Here you go:

red: 12v power source
orange: ignition
white: illumination
black: ground
yellow: external wiring option(for an audible buzzer I belive)

I got the power and ignition source from my turbo timer harness. Illumination signal I used the light on the cig lighter. Ground goes to ground. Do yourself a favor and solder all connections and cover with heat shrink tubing so you don't end up with a loose connection to track down at a later time. Hope this helps.
