My 1st attempt at installing a new head hasn't gotten very far. I have a 16 pin female connection hanging out of my console (image 1), but I need the 12 pin male end (which I have) connected to the new head (image 2). Haven't been able to find an adapter. Is my only option to strip & splice? That seems pretty extreme for swapping a head unit, but I can't seem to find any simple options & no one at the local car audio shops seems to know what I'm trying to say.
