Does any body know what this plug is for?
Plug is right by the horns on a 1991 Ford Mustang Convertible LX

I actually think that’s the Daytime Running Lights plug found on the 1990+ cars. A shorting plug is installed on the US cars, which is what that appears to have.

Canadian cars would have a module installed there

I agree with Mustang5L5, it would have 7 wires coming out of it.

Yes, daytime running lights became standard on all Canadian sold cars in early 90's, all makes, all models.
