the lights above the tach he is pointing to are....
from L to R

mystery light not on USDM clusters(I'll keep looking)
Oil pressure
Alternator

like this...



**edit** I couldn't find anything, but it looks to me like it's engine temp or something like that.

 

I'm not sure what the light means, but it looks like an exhaust temp or converter(sp) light.

 

 

It very well could be. RX-7's have those, it's basically a thermoswitch attached to the floorpan. When the floor gets to hot, it triggers the light.

Go for a good hard drive, then look under your car. If the cat is glowing, it needs replacement ASAP. If it isn't glowing, you may still want to take it off and have a look inside (when it's cool, of course.)

 

You have LSD right? Could it have anything to do with that, like low fluid, or tranny temp?
