Does anyone sell or could one hook up (such as a temp. sender) a warning light to alert you of a high EGT reading? Sometimes it would be nice to not have to watch the guage while "gettin' it" on the road or track. I know some of the digital guage setups have a "warning alert" programmed in them, but I and alot of others use the standard guages and are forced to keep one eye on the road and the other on the guage. Any ideas?
