The Most Devastating Engineering Miscue Found in Early A-Bodies

Thanks, I don't have that wiring diagram. So the park lamps are connected to the tail lamp circuit. Makes sense because it keeps current load off the headlight contact and shares power with the low current tail light draw. I must say though, that my original harness for the headlight switch does not do this, instead, it's the same as the factory manual, with the parking lamps on P. I'm thinking this change may have happened after my car was built (12/14/64), and early Barracudas didn't have this connection. Park lights would only come on when the switch was pulled out half-way.
