I give up! How do you dim that gauge anyway?
Okay, I have read must be a hundred posts over the last two hours looking for info on how to hook up greddy 52mm gauges so that they will dim with the regular lights. I tried to apply the thread from here on the Omori gauges but its not the same.
I have two gauges Boost & EGT
I have four wires on each gauge.
They are
Black = Ground
White = Illumination
Red = 12v constant
Orange = ignition
I ran them into the fuse box and I can get them to come on only when the light comes on but not dim. Is this even possible?
I will probubly be using the wires in the clock though when I do the finished wiring. the wires in the clock are:
Blue/Red:+12V
Black:Ground
Yellow/Green:ACC
Pink:Light
I am assuming here that the yellow/green:acc is the ignition.
Any help would be GREATLY appreciated.

you gotta look for the wire the dims the gauges.. never really tried it on a wrx but when i hooked up a tach onto my friend civic, i jus took the dimming **** out and tested it on each wires.. if the lights on the gauge can dim, it's possible... i guess jus find wiring diagram for the car

OK....pull the radio out, carefully, and there is an unused plug on the radio harness...peel the tape off it and use the plug for gauge light(only light!!!) power. I have Autometer gauges and I use a 168 bulb in them, colored with a green marker and they match as close as possible to the '02 gauges.
There ya go, Zipps

I see the plug thanks. does it matter which wire goes to the light wires on the plud? I only have one illumination wire the other two that are powered are the 12v continuous and the ignition. I am assuming the ignition? then run the ground and the 12v someplace else. I will give it run. Any other possibilities would be appreciated thanks.

The dimming circuit in a subaru is a little different than other cars - most use a floating high (0 to +12V) and a fixed low (ground - 0V). Subaru, on the other hand, thought it would be cool to use a fixed high (+12V) and a floating low (0 to -12V) - if you have a mechanical gauge, you can get the gauges to dim by using those two wires as the high and low - for an electronic gauge, it gets a little more complicated, and extra circuitry is required (see below)

Okay, WAY outta my league in the wiring catagory. So it would appear that im going to be WAY better off to just wire it in normal and deal with the light staying on at a steady illumintation when the lights are on. They really arent very bright and that was the reason for trying to hook them up to the dimmer in the hopes of increasing the light emmited. Thanks everybody, been a big help.
Happy turkey day to ya!

If your gagues seperate the light from the rest of the gauge power...you are there. Just use the plug on the radio harness...polarity won't matter for the lights, just get some spade connectors from Radio Shack and crimp them on wires to go the the plug...now power for an electrical gauge like an EGT needs to be tapped form elsewhere...I used one of the unused relay plugs in the fusebox for ign. switched power.
The bulb in the gauge may be changed to regulate the amount of light they give...that's why I put #168's in my Autometer gauges...they simulate the amount of light the cluster gauges give almost exactly and dim at a constant rate with the cluster gauges.

They are both electronic gauges by greddy. They have the four wires and one is for illumination, the other two the red, constant and the orange ignition, then one ground. I guess thats why im confused about what two to use on that harness Scotty. THe 12v I can run to the clock or the cig. The ignition to the clock or fuse box. The ground, well to a ground. But that only leaves me one wire.

I run my gauges at full-bright, anyway, so I just wired my Omori electronic gauge up using the illum lead on the clock (which is 0 when the lights are off, and +12V when they are on) - I have the stuff to set up dimming, but haven't bothered yet (you need to grab the other illum wire from the radio or somewhere like that)

You must think of it as 2 seperate electrical entities.

With a mechanical gauge, the only circuit is the light circuit, so you can get away with using the high and low illumination leads, thereby preserving the normal dimming function.

I guess, by accident, that some Autometer gauges do indeed have an advantage over some of the other brands....and it isn't quality...
I was unaware of the facts of above post and apologize for any confusion that I may have caused.
Thanks, DrD for setting me straight.
