Headlight question.

I've got a 69 Dart Swinger 340 that I pulled the harnesses and rebuilt them with new parts where needed. I also eliminated the ammeter and bulkhead connector. I connected the ammeter connections and used posilock connectors to replace the bulkhead connector.
Anyway, everything seems to work fine but the low beams come on when I pull the switch for parking light position. The low beams stay on when the switch is pulled to the final position (as they should). High beams work correctly, Oh, ya I also installed the "crackedback" headlight circuit.
Any ideas?
Thanks in advance,
Jeff
