97 E320 / E430 / E300 W210 Need instrument cluster info

[97 SL320]

Two things:

Anyone have a wiring diagram for the instrument cluster plugs? I want to power one up outside of the car.

Second, 1/2" below and to the right of the speedo needle center, there is a 1/8" diameter red dot that has a LED behind it. Any idea what this is for? It is pretty hard to see, you really have to be looking for the dot.

Thanks

I found out what the red dot / LED is. This senses ambient light to adjust back lighting for the LCD odo, clock, info center.
