What will this part number work on?

D3TZ-11654-A it is a headlight switch.

From everything I can find, this may be a replaced part number. I see the D3ZZ -A for 67-76 trucks and the D7TZ-A for 78-79.

Super confused.

 

1980-2002 Ford F600/700/800/650/750 All Engines
2004-2006 Ford F600/700/800/650/750 All Engines
1980-1989 Ford School Bus Chassis All Engines

 

If you think you were confused before...take a gander at this menagerie of headlamp switches! The following list covers 1965/79 F Series Trucks, 1975/79 Econolines & 1978/79 Bronco's.

Some of these switches fit other big trucks, but it would take me an hour to type all the applications.
