Of course not, usually a little wire AUTOMATICALLY plugs itself to the EGR warning light, all by itself.
Then, while you asleep, it slowly snakes it's way down the front of the fiberglass tub, through the tunnel and back to the engine where an EGR valve magically pops up for it to attached itself to.
While you get up, shit, shower, shave, and sit around. The system tests itself to be sure that it's operational and by the time you leave the house and get into the car . . . it's all rockin' and ready to run.
As if by magic.
No REALLY . . . you wouldn't have to TOUCH that EGR thingie.
Now, on the OTHER HAND, if I PERSONALLY was gonna pick up one of those four quadrant combination gauges (which I have) and didn't have an EGR equipped engine (which I don't) or an open fuel filler door alert switch (which I don't) or most of the other modern touches that new cars have and that seem to require warning lights for.
I would open up the gauge and remove those two red transparent plastic panels (which I did) and sand them down smooth to remove the white symbols.
They I'd paint my OWN white symbols onto them instead. Symbols similar to these, perhaps.

One would be for the front fog lamps, another for a halogen bright back-up lamp and alert horn, one to show when the brake lights and rear running lights were turned off (not that I would EVER out run a cop and NEED something like that), and another to let me know when the front lid wasn't shut and locked down.
That's what I would do, since it's going into an Outlaw, and we Outlaws tend to flaunt our exhaust gasses, rather than recirculate them.

I don't recall if Pearl is running with 914 gauges or not, but if she is, and you would like me to re-work a gauge for you with little hand-done symbols and such, I'm all in. Just grab up a gauge and send off off to me, we can figure out what symbols you want and DONE ! ! !
