Report "I have an F550 that the instrument cluster is going haywire. All the “dummy“ lights are on, the speedo, tach, temp, and fuel gauges does not work but the oil pressure and battery gauges do. Here’s the fun part, if I turn either blinker on, it all works properly, if I go under 15 mph, it all works fine, and if I hit the brakes it all works fine, until I turn off the blinker, let off the brake or hit that 15mph threshold! I’d be happy with even a wiring diagram at this point"
