I've spent way t o o much time on a restoration, to start with. (sourcing 45 year old air for the tires, etc.)
I've got one relay that clicks and stays that way( the subject of the capacitor replacement, where photo was lifted) Then, I have a ebay purchase that doesn' t do squat, thank you very much $30. later.
So I started to look at automotive timer circuits, ones that open and one's that close, to see if they could work......not finding an available Bosch replacement.
I admit I fell down the rabbit hole.
I started questioning why not have all the ground circuits connected, it's for low brake fluid, front vs. rear brake circuit.
It seems only relay for the "fasten seat belt" 5 sec. notice is desirable.
C. It's more to think about than which TV episode, I'm up to.
Thanks for the reply. But am I wrong......about the grounding???
