I have a 97 Blazer LS 4dr. 4x4. I dont have a tach. Im not sure if it was an option but as im not the original owner Im not sure. How hard would it be, if possible, to install a tach?

Easy, way too easy if fact. No need for one really unless you wanna drive standard by it or do some serious off-roading. You want one badly enough go to pep-boys, autozone, etc... They'll fix you up. Peace-

If you want to put an aftermarket one in, not that hard go get one at a parts store and follow instructions. If you want to put a OEM one in, you need to find a cluster from a truck that has one(the wreckers) take out yours and install the new one. The connections are there already in the connector pretty much plug and play.

Thanks blazes9395. I didnt specify clearly, I want to put in an OEM cluster. I didnt know if cables needed to be ran or if the connections were already there on a blazer that didnt come with a cluster w/ a tach.
