ok, i just got in my new tiny tach in.now my question. from the tach there is a single black wire,which then ties into a white wire which is the ground,then there is a single red wire that comes out from the black an white wire an wraps around the spark plug wire? is that all there is to correctly installing one?

yes

You will also need to ridgit mount yore TinyTach in such a fashion to be legiable .....
