Guys,
I just got a replacement seat belt warning relay and associated wiring. The relay is what appears to be a used part. I'm curious if anyone has wired this up? If so, was there a ground? It looks like the bolt tab on the relay is broken off, and I suspect this is what provided ground to the relay and associated circuit. This is what I picked up: http://www2.cougarpartscatalog.com/10003191.html
and http://www2.cougarpartscatalog.com/store/p/13152-Wiring-Harness-Assembly-Seat-Belt-Reminder-Standard-Used-1968-Mercury-Cougar.html
Also if you know what type of fuse goes in the wire that would be helpful as the fuse did not ship with the wiring-
Best,
-Tony
