Tach Solution?

[ammachine390]

does anyone know if the wiring is there to install a tach into a car that has the clock?? hoping the wiring is there to do this tach swap. my new station wagon just has the clock. both my sx4's have tachs. im going to be hunting for 3 frod tachs now. be nice to know if it has the wiring for it.

I don't think the wiring is there if you have a clock. However, the only wire you really have to run is the tach signal wire, which just gets hooked up to the negative post on the ignition coil. Other than that, the tach just needs a 12 volt power source and needs to be grounded, which you can tap into near the fuse box.

I looked and did not find a tach wire.  ammachine390 is correct, in that the only wire that has to be run a long way is the tach signal from the ignition coil.  I grounded the new tach to a screw on the instrument panel, which is how the original tach is grounded.  I ran power for the tach from the 12V wire going to the instrument panel.  Give me a couple more days and I'll get a How To posted.
