I found out where breaker should
go but 1st...
Like I mentioned above under grey cover is terminal block:
Then I was able to get it all the way off to see what's nderneath:
But I did find where breaker should be on back side. I had to take out glove box. But there was only one breaker! The one for the power seats. I see contacts for other stuff. I tried to test for voltage but I need better adaptor. My leads wouldnt fit in and I tried wire but I dont think I'm getting good contact. None of the numbers matched up on schematic to panel either. There are like 5 contacts but 3 are in a row and you can't use 2 because of the power seat breaker.
So I go to local autoparts store and they show nothing for breaker [X(]
But, my neighbor has an 04 Impala and I'm going to see if they will let me look at theirs.
Also on the radio board in back there are 3 wires going to it and all same color, black. Must be junction in rear piller but I'lll worry about that later if need be.
