ex/si cluster in a dx

had planned on a b18c5 swap into a 92-95 civic and i dont want to spend alot on the car itself, i come to realize the dx is way way cheaper than the ex in the same year but it doesnt have the tach so can i take out the dx cluster and swap an ex/si cluster w/ the tach or is there more to it?

Say "232",plugs are already in there ...plug an play ...easy install...
