if you wanna remove it from behind the cluster, just reach as much of you hand as you can back there, and pull on it while twisting..... i'm 99% sure its not threaded into the cluster..... it is kinda hard to get out, just pull on the connector and it will come, make sure your electrical connectors are out already, if memory serves me right, taking those connectors out gives you a bit more room to reach your fingers back
hope that helped
