No start, wire on coil

Morning Ya'll
So after removing my coil to upgrade and to reroute my fuel lines on my 74 valiant slant six I have a no start condition. Cranks all day however I'm pretty sure I gomer pyled the coil. So a wire similiar to the diagram broke from the coil, do I actually need it? 2nd question is the wires that come from the harness go to the negative correct? Meaning without the wire going to this wire contraption nothing is run off the positive of the coil?
