Anybody got a 1975 Electrical FSM? Have Questions...

I'm currently buried in the dash of my Charger, trying to trace some minor irritations that the car has had since I've owned it. I've got the books for 1976, trying to troubleshoot the 12-point block for the instrument panel, as most issues are focused at that location...and my luck, the schematic for '76 isn't lining up to what is in my Sept. 1975-built car. I just want to see what difference there could be between the two model years. Can anybody help out?

One side.

Other side.

From the ‘76 book.

Does look like an arc or burn on that firts pin from the right in the secoond pic. I would inspect the trace on the PCB that corresponds to that pin

Found these Not 100% on the accuracy as they appear to be from a Chiltons or equivalent

Select 1975
download it
Open the zipped folder

there are other models in the zipped folder. Possibly somebody swapped a harness thinking they would be the same ???
