37silverstreak Posted December 16, 2018 Report Share Posted December 16, 2018 Hey guys, Just curious, when did Plymouth start incorporating the starter circuit into the ignition switch? I'm guessing that my early '49 Plymouth P15 ( i prefer referring to her as a '48) has had its ignition switch replaced at some point before I bought it as the switch has 4 terminals on it instead of 3. It has the spring loaded second right position that allows you to crank the starter from the key instead of a button and also has a left key turn position that allows you to run the accessories without turning on the ignition. I'm going to keep this switch in the car as it was what was in the car when I bought it and it seems to function fine, but it did cause me some headaches trying to figure out the wiring as the P15 diagram shows a 3 terminal switch. Thanks! 1 Quote Link to comment Share on other sites More sharing options...
Adam H P15 D30 Posted December 16, 2018 Report Share Posted December 16, 2018 I believe 49 was the first year. Quote Link to comment Share on other sites More sharing options...

JerseyHarold Posted December 17, 2018 Report Share Posted December 17, 2018 FWIW, the ignition lock cylinder is the same from about 1947-1967. Any parts store can get you one. 1 Quote Link to comment Share on other sites More sharing options...
