I did a fair bit more investigating and there is definitely more going on here than I thought! Anybody dig into the temp light before, or am I in uncharted territory? Either way I am up for the challenge but if anybody can add some knowledge I would not complain!
As it sits now I think there is some information sharing going on between DME, the dash, and both parts of the sending unit(or maybe I blew something in the dash) so planning on looking in that direction next.
