I found this plug behind the glove box on my 1983 K10 while I'm trying to figure out why my OD is not working. Does anyone know what it goes to??? Hoping this is not some sort of ECM/PCM plug. I can't see the actual casting numbers on my tranny but it has no pressure plugs so I'm thinking someone threw a later model tranny in here & they couldn't get the OD working either. Help!!!!

As you can see there is nothing back there for it to plug into.
