Okay, here's the deal. My friend was telling me how he wired up this Tach, by just wiring the wires to the back of his gauges. He has a CRX with a tach all ready in the cluster. Well, when I was doing this I messed with the screws in the back. The +/-/T later finding out the T stood for Thermostat. Now my thermostat doesn't register. This sucks. Heh. Anyhow, I need some help getting it to work again. Another thing, if I ripped the cluster out of a 90 CRX (Same year as my Hatchback) would it fit in? Would the stock tach work?
