BUT no signals or hazard lights. I believe this is the flasher (after eliminating the other relays!)

There are 4 connectors, but only three had wires :
White -- L
Blue -- X
smaller double brown - P
what should go to the other terminal? This non-connected terminal is different as the attaching lug is outside the base, rather than just a protruding terminal.
Any thoughts or help would be appreciated.
Thanks,
Troy
