E4OD Shift solenoid - 2wd or 4wd?

[Oldtowntrucks]

Gotta replace my shift solenoid for my '93 E4OD, I know it has to be within the 89-94 for electrical reasons, but does it specifically have to be a 4wd or 2wd model solenoid? I've seen some listed as either or but it seems like it almost doesn't matter. My trucks a 4wd.

Can anyone confirm that? Thanks

They're all the same.
