if i remember correctly, the yellow bullet connector plugs into the door switch, which completes the ground circuit when the door opens, and breaks that circuit when the door is closed.
the travel path for the console harness goes from the kick panel, under the wire tunnel [the fold over tin protector] with the tail light harness, exiting it in an opening by the middle of the driver's seat, then following a depression in the floor to the console.
there should be a couple of screw holes there to attach clips to hold the harness in the floor depression.
that is how my 69 is, and your 70 should be the same.
