At least on the analog-clock versions, the sender is attached to the pin nearest the high-temp end of the scale, and the other one gets +10v. But say more about what you're trying to do? It sounds as though you're trying to hook up two gauges to the same sender -- that won't work well. The gauge that belongs to that sender will read low, and the other will read -- lower than it would if it were connected by itself. Could be low, high or in the middle, depending on the sender. david
