I want to install a tachometer on my 95 corolla (actually a geo prizm...but lets not get technical) so im going to go to a junk yard and grab a whole new guage panel/cluster, spedomemeter, gas, temp etc. and install it.
Before I do this, Im looking for help as to how to know weather or not my car already has the hook-ups. I checked for thr requisite green wire on the ignition coil, and it appears to go to the speedometer cluster. But is there something tell tale i can check for, b/c right now, after I have removed the instrumentation panel, I can't just look and say, 'oh, there's the hook up!'.
Would it normally be the case that if the car doesn't come with a tach, that the hook-up to the coil would have to be done?? Or are the leads already in place on some makes/models??
Your help appreciated.

If you get an instrument cluster from the wreckers, then it will have al the connections. They wont put a seperate wiring harness into a car without a tach. all cars have all the wiring. there are 3 connectors on the back of the cluster, I changed my no tach cluster to one with a tach in about 6 minutes, and everything worked perfectly.
