1974 duster seat belt interlock module removal

The interlock just needs unplugged from the seatbelt under the seat to no longer function. I'm pretty positive that I traced mine back to the dash and pulled the floor harness eventually...and I don't recall having to splice anything. But for all I remember the floor harness may still be under the carpet. I am 100 percent positive though that simply unplugging it, disables it.
