67-69 Dart Ignition Switch Pinout

MANY guys have trouble visualizing the feedback/ loopback problems that can occur if the IGN1/ IGN2/ START circuits are screwed with!!!

My first "trip down that road" was in the mid 70's when I swapped a SB Mopar into an old Landcruiser----and used a GM column, which has no such circuit. (The "IGN2" or bypass function is on a GM or Ford starter solenoid/ relay)

I ended up using a big diode to "replace" the IGN2 circuit. Your choices in such a case are, add a relay in parallel with the start circuit, use a diode as I did.
