interrupt wire breaks the circuit if i recall correctly yeah it was a black wire but it should go from purple to the interrupt switch then down to positive side of coil on a points system. i know some actually grounded the coil wire temporarily killing coil , but i didn't like that because what if it got stuck and just kept grounding the power wire and started a fire?make sure its a normally closed switch if not and its the normally open then you will have to wire it differently normally open grounds circuit normally closed completes circuit.
