i have an si, it had a cx cluster, put in an ex cluster...nothing works. temp, fuel, tach, speedo, lights. when i turn the key on, engine off, the only light that lights up is the battery light. no srs, ses, or anything like they should when you do that. when i turn on the right blinker, it lights up on the dash, left turn does not light up. i checked every fuse known to man and nothing is popped. i tried putting the cx cluster back in, and it is doing the same thing. wtf

 

I sucessfully replaced a stock DX cluster with an Si cluster. The DX did not have a tach, but the Si cluster did. I just plugged in 3 of the 4 connectors, and EVERYTHING works perfectly. However, if you have 4 connectors, maybe you need a 4 connector cluster.

 

Try checking all of your plugs. Make sure they are in tight. Shouldnt be the new cluster if its doing that to your old cluster.

 

got it. bad ground

 

where is the ground?
