I installed a pyro, tranny, and boost. All have the same ground, ignition hookup, and constant battery supply. Boost works fine, but when I start my truck, my pyro and tranny jump all over the place and eventually the needles go as high as they can in temp. The probes are good, I unhooked them and the gauges continuously jumped everywhere. Any ideas where I went wrong? All connections are solid, ground is good... My ignition power source is my ignition fuse, my continuous power source is my headlamp fuse.
