Installation location ?'s answered, however, what about wiring? All three guages need power for lights, you guys running one hot and one ground and splicing all three behind the A-Pillar? What about the power source for the pyro guage? Searching the archives I found lots on where to mount sending units for guages, not much on the actual wiring itself. BTW, I will be mounting Autometer Ultra Lites, Pyro, boost, and transmission. Thanks in advance.
