Go to Official Ford Parts Site
, enter your VIN, point to "Electrical, Lighting, & Body", and click "Switches". Change results per page to 75, find "Turn Signal Switch", and post what you find.
For a '93 Bronco, the options are SW5591 with red hazard button (original), and SW2485 with black.
For a '95 F150, only the black is recommended.
For '96 Bronco, both.
For a '95 F350 CC dually PSTD, only the black.
If you log into that site, you can save VINs and label them so you don't have to re-enter them each time to look up PNs. I have a bunch saved so I can compare things like this. But another way to do it is to click the "Buyer's Guide" tab, enter the PN, and look at the list of vehicles using that part. For SW2485, it's:
Years . . . Make Model Engine Qty per Vehicle
1992-1996 Ford Bronco All Engines 1
1992-1997 Ford F Super Duty All Engines 1
1992-1996 Ford F-150 All Engines 1
1992-1997 Ford F-250 All Engines 1
1992-1997 Ford F-350 All Engines 1
So as you see, trucks over 8500 use the same MFS as those under.
