well i sold my CTR cluster and put my Si cluster back in and the illuminating light for the cluster does not want to work andall the connections are connected, can you guys think of a reason why this is happening?

 

Check the bulb?

 

You might have damaged a bulb when you removed the cluster the first time. Check those.

 

One light? Or the whole cluster?

 

Did you check the fuses? 9 times out of ten that'll be your prob.
