I have a 95 civic dx without a tach cluster in the dash. I noticed that on the harness behind the cluster there was a connector with a cap on it. Is this connector for the clusters with a tach or do i need something else?

 

does anyone have any idea?

 

not sure how it is for the 92-95 civics, but for the 88-91, you plug an Si cluster in as is and the tach works...
