I've posted a number of messages on this forum and I appreciate everyones
help, so thanks to all.

My concern today surrounds my '98 Civic Lx's lack of a tachometer, which I
would find very useful as my car is equipped with a manual transmission.

As of late I've been considering replacing my OEM gauge cluster with that
of a similar year Si or Ex model; both having the tachometer I seek.

I've asked a few Honda dealerships if installation of a new gauge cluster
would be a simple process of removing the old, and replacing it with the
tachometer equipped cluster - their answer was that such an operation would
necessitate re-wiring the car to the tune of a few hundred dollars. I have
neither the will nor the inclination to spend a few hundred dollars fooling
with the wiring in my car, nor to install an aftermarket tachometer.

Acquiring an Si or Ex gauge cluster is a non-issue for me as there is a
ready supply of them on e-bay for little money.

Does anyone have experience regarding this procedure?
