Happy Holidays everyone, I hope ya'll got what ya'll wanted for Christmas, I am trying to hook mine up right now. I am tryin to hook up my fuel pressure gauge, and am wonderin where ya'll tapped in for a power source. Did ya'll use a hot ignition wire, or a constant hot, like the cigarette lighter wire? Fixin' to go on a trip, and would like gauges in before hand, Thanks in advance, and God Bless, James
