                                                          The pick up coil sits at the base of the distributor. As the camshaft spins the distributor shaft a magnetic gear passes by the coil, it "trips" the coil to activate the ignition coil. The ignition coil sends a spark to the rotor which will be lined up with a post on the cap going to the spark plug.
