If it has a green wire going to it then it is the heater control valve. Yes, it is electrical and it is hotter than the hubs of hell in normal operation. I inadvertently touched it with a finger tip and it almost immediately blistered (temp not related to coolant temp). It is part of the Vintage Air kit.

Maybe the owner can tear himself away from vacation planning and post up some more pics of progress...... I know for a fact there has been some...
