I've got an 88 Civic DX 4-door, just picked it up for extremely cheap and in excellent condition. My Question is this.... I used to have an 89 civic LX 4-door, and loved the gauge cluster. If I am able to find a cluster with the tach, right now it just has the huge fuel level and temp gauges, would this be a direct bolt in, or would I have to make wiring modifications for the tach to work? Thanks for the info!
