I just picked up a spark plug connector (000 156 57 10) and ignition wire connector (000 159 14 38) and having a bit of a problem trying to figure out how to attach the wire to the spark plug connector. There doesn't seem to be a screw type of connector in the connector like with my Bremi wires. Instead, there is what appears to be a circular connector in the rubber boot. Does the ignition wire connector screw into the spark plug connector, and if so, how do you attach the ignition wire connector to the wire?
