Hi Toyota nation. I recently aquired a base model 1997 corolla (no A/C even) and it did not come with a tachometer. I sought out a buddies 1996 corolla dx and paid him $20 to swap out his cluster and mine. I assumed (and read in multiple places?) that the guage clusters are plug in play however my tachometer is currently not working? Do I need to run a special wire to it from the igniter? Shouldn't it be working as is? There is also currently a bulb out behind the tach but I don't hink that would affect it's ability to function.
