Terminal 7 on the controll box goes to a two terminal junction box under the battery. it hooks to the green point condensor lead, the ground hooks to the other screw on the juncton block. the timing controll switching box also hooks up to this junction block, this is where it gets its RPM signal. there should also be a brass lug on the terminal 7 screw. This is where to hook up a dwell meter when setting the points.
