Ok here's my question I have a 1998 xj with a 4.0 and an ax-15 its on a 8 inch long arm kit with 33x12.5's and a tach would def come in handy needless to say I have the dummy cluster.... Is the cluster with a tach just plug and play? Or do I have to change other things?

Any info would def be appreciated

 

try searching, there are lots of threads on this.

 

Yes it's plug and play. You'll just need an oil pressure sending unit and a temperature sending unit.
