The yellow and black wire in the picture below was pulled off the fuse panel decades ago. I need to reattach it to the panel. It likely belongs on fuse #7 (the first blue fuse below the white ones). As you can see in the picture, there is an open spade terminal at fuse #7. The wiring on Pushbutton car is different than later Panteras. I am hoping that someone with a similar car can look at their panel and confirm the location of the yellow and black wire.
This is the best picture I have of the fuse panel in PB #1239.
There are a lot of different color fuses in mine and I can't see a yellow/black wire on fuse #7. ( in the picture)
The fuse panel and wire loom are out of the car at the moment so I can check tomorrow if there is another yellow/black wire.
It looks like your yellow/black wire is going up to fuse #2 or #3. My wire will not reach that far (maybe it has been cut off). On my car the yellow/black wire is the power source for both radiator fan relays and ultimately the radiator fans.
