Purple wire feeds the gauges and supplies ignition. If it runs (and also turns off, thanks TKS), your problem is probably there. Gauges are often (always?) daisy chained, so if the first gauge isn't powered, none of them will be.

purple from the switch connects to the purple wire that is daisey chained thru the gauges, the other goes to the main harnes to the engine

both purple wires are connected to the ignition switch...What a mess of wires under there. I'm going to start cutting zip ties and dive in.
