I have read and searched but cannot find the answer. If you're adding the Edge J/A and pillar gauges where do you tap for the second Thermo Couple?
I have an Edge/Attitude and Autometer pillar gauges. I piggy backed the Autometer gauge on the same thermocouple as the Edge. I tried them both separate and together and not enough difference in readings to worry about.
Not the black and white wires, I know what they're for. There is a red and black wire coming out of the bottom of the gauge. I'll take some pics later this afternoon and post them. I though it might be for an amplifier to boost the signal from the thermo couple or to supply power to move the needle.The Edge & Autometer pyros are the same thing, but the one from Edge is longer. The black&white wires on the pyro are for the lightbulb, power & ground.
