Reg,
I support what Dr. Benz (Dan) says.
Doesn't look like anything for an emergency flasher.
You need to have a pull switch for an emergency flasher if you have one; however, your assembly around the original flasher relay looks stock to me. So perhaps you have no em. flasher.
As to the warning light you have found on your dash ... does it illuminate? In red ... really??
It looks to me as a control light for the trailer hitch (flasher) and those illuminate green or slightly yellow.
Perhaps there was once a hitch under your car.
Good luck,
Achim
