NP203 Lockout switch part number

Hello all,

Does anyone know the part number for the 1979 NP203 transfer case lockout switch? Apparently they're pretty tough to come by.

Thanks.

So says Number Dummy....D2TZ-7E440-A .. Switch (Motorcraft SW-1112) but when you run that # you get a trans spark control....

Are you talking about the switch to make the "Locked" light come on? So your 79 has the light already under the dash?

Yep, that's the switch that I'm talking about. I have this case in a '61, so it doesn't have the light yet.

Well read those attached threads, the light is in heavy discussion in them.

I just want to confirm for anyone else searching that Motorcraft SW-1112 is the correct switch and is visually identical to the original one in the NP203 transfer case.
