I have finally decided to move from the "dreaded points" and install pertronix ignitions in my 3 Kadetts. I am familiar with the wiring on a GT regarding the red wire to the resistor wire connection on the fuse box. However, the resistor wire on a Kadett connects to the back of the ignition switch. Should I splice into the wire connection?
Thanks,
Gerry
