I don't know I bought it set up this way the horn has never worked as long as I have had it. Would that info help with figuring out which switch is currently in it?
When you say "manual" are referring to the steering or the transmission?
If it's the original switch, it should be marked with an engineering number.
Marked D3TA-13B302-AB = P/N D3TZ-13341-A, 73-77 w/ manual trans
Marked D3TA-13B302-BB = P/N D3TZ-13341-B, 73-77 w/ auto, no cruise
Marked D8TA-13B302-BB = P/N D8TZ-13341-B, 78-79 w/ auto, no tilt
Marked D8TA-13B302-CB = P/N D8TZ-13341-C, 78-79 w/ manual trans, no tilt
So I have to use the switch from a 78 or 79 because that column is in the 77 truck? I had wondered since the horn didn't work that it might have the 77 switch currently.
