ok i got my buddy's eg si cluster...and i want to put it in my 95 dx. so i gets to removing mine and wat do i see..only 3 plugs and the si needs four.not quite plug and play ..now does that mean the 4th plug in the back of the si cluster is uselessor do i have to go buy a clip and do some wiring?

 

Plug it in a see if there is a problem.

 

the si cluster probably has slot for cruise control which is green i believe, since you have a dx which doesn't have cruise control,yours doesn't have a harness for cruise control (at least this applies to 6th gens, not too sure on 5th gens though)

 

ej6buddy thanx the plug is green so it is worthless.. great help. thank you

 

Exactly, i got an Ex cluster and it works fine. it had an extra plug too, but i had nothing to plug into it, and it worked fine

 

I never thought of that. I have an EX so I have cruise control and the green plug. Sweet.

 

Nice to know. I was wondering what the green plug on mine was for.

 

When you plug in an EX cluster to a DX, does the tach work, or do you have to do wiring for the tach?

 

plug and play, yes tach works.

 

The tachometer pickup is wiring into ALL honda civic models, if you get a cluster with tach, and hook it up, then it will work, it's as simple as that.
