happy new year!

the defi d wiring instructions for my temp gauge call for:

dimmer - white
power - red
ground - black
ignition - orange

(the colors are the ones from the gauge)

the only one i don't know where to pull from is the 12v ignition. this is not the same as the 12v constant (power)... also doesn't the ignition just send a brief voltage? if so.. what's it for? to trigger the start-up sequence on the gauge?

gauges have a self check sequence built in. The ignition starts this. It also makes sure the gauge is not hot all the time. I tapped everything off of my headlight switch. I am pretty sure it was black with a red stripe that was ignition off of the headlight switch, but you can confirm this with a test lite.....

thanks again.

these things are a much bigger pain then my autometers were.

Frustrating ... but ocassionally better is harder ... Nice Color ;-P

Yes, I believe it's the 'switched-power'. To start my Defi boost gauge when the ignition is turned on. I connected my switched and constant powers to the fuse box. Switched power is in the middle while constant 12v was on the left.
