They changed positions of the flashers from the older locations.

Some are mounted under the dash attached to the steering column structure so they could be more easily heard.
Then they placed the "Electronic 5 prong flasher" to a block it shared with some other relays behond the center of the dash. If you purchase one you will have some idea of just what you are looking for. It is definitely different from a typical relay .

 

the flasher relay for my e350 has only three pins auto store says it is the right one for my 2005 e350 super duty cargo an mahalo god bless

 

If you have a Ford Dealership around, check with them, they should know.
