well guys thanks for the feedback, I think hes just gonna go ahead and order the whole cluster... (hes rich, so it really doesn't matter to him if we cant get it to work or not).
I had some ideas while i was looking over the haynes wiring diagrams for the civic instrument cluster... It might work.. it might not.. but if i figure out a way to make this work you guy will be the first to know and expect a how-to if it is succesful.
If in fact you can get the tach to work and not the speedometer to, i will just probably end up custom making a digital speedometer and a driver for it that will run off the varying voltages the stock civics wiring gives off.
Well thanks guys, I will be posting my progress soon..
peace, Eskie
