I have a '94 Civic DX. I didn't want to add an aftermarket tachometer unless my first choice didn't work. I bought a cluster from the junkyard that had a tach and installed it. Everything works but the tach and the speedometer. The tach jumps slightly at idle but the speedometer doesn't move. Should they have automatically worked when installed or is there a fuse or connection I need to hook up? Or how can I tell if they are broken? All help is appreciated!
