I have known more in 75 than in 74
for a late 74 control unit I have an orange box, what is supposelly is a canadian unit and is not interlocked, but works the advertising functions. already mounted and works as stated just for buzzer and lights advertising signals PN 3501371
My conclusion about is a canadian unit was simply because I got the rallye harness from a Canadian Guy on ebay ( about 4 years ago ) with the control box attached
on Mopar parts catalog this orange unit is stated like to AUTO and also MANUAL cars after 2-01-74
In_The_Pink...the one you grabbed me with PN 3746849 is labeled to Manual cars ( excepy C bodies ) from 10-28-73 to 4-01-74
the is the actually one I have with interlock function apparently damaged:
this are two one ebay right now:
