Instrument Cluster Removal

What a cluster! ;-) I think someone did some custom wiring. Well I thought. Looking at another pick on here I see that spade lug evidently does go in under the voltage controller? Now the red wire butt spliced in seemed to go nowhere unless I pulled it loose from something because I found it connected to nothing. See next pic.
