i got a civic type R cluster in my EJ8 i was wondering what the yellow and orange connector harness in the back of the cluster do because the green connector is not connect. I look at my home boy which has a stock cluster and his green and yellow connector are hook up and orange one is not. I have a DOHC and he has a SOHC. Some one help me cause i want to get an si cluster cause my type r cluster tach cut out when i hit vtec so i believe its going bad. Do a Si cluster has these connectors so i can plug and play thanks?

P.S if you have an si cluster just look and tell me what is hook up. THANKS.
