you may have already gotten the info, but
here is how i lit up my gauges.
http://home.comcast.net/~cookpaging/...augePower.html
this particular way is for if you want the
gauge light to dim with the dash lighting.
for 12vdc that just comes on and off with
the light switch, i'd have to look at the
service manual when i get home.

This past weekend I was installing my Autometer vacuum gauge (the carbon fiber one, it looks awesome!) and I wanted the backlight to come on only when I turn the lights on. But, found out by using a volt meter, there is no wire that will go 12v when the lights go on. Instead, there's a wire that goes to 0v when the switch is on, but 12v when it's off.
:/
So it looks like I'll have it setup where I use an add-a-circuit but have it come on with the ignition.
Unfortunately I could not hook the gauge all the way up b/c the vacuum tee that comes with the gauge is too small for the vacuum lines in the car. I'm going to tie into the one above the fuel rail that connects to the fuel rail pressure sensor. That's where I read others doing it (although they were hooking up a vac/boost gauge) on the net.
:/

I have the same gauge and mine worked perfectly. All I did was cut into the vacuum line and put the T in. Then I slid the crappy little white air line into the supplied reducer and put the reducer onto the T connector.
I hooked my wires up with quick connectors, using a previously run ground wire and a power wire from something else.
So for now, the light is on whenever the car is on. I may change it later.
