The Most Devastating Engineering Miscue Found in Early A-Bodies

Since this is the first '65 Barracuda I've owned, I never knew the park lights came on with the headlights. I've been studying the wiring diagrams in the service manual and I do not see any indication where the connection in a Barracuda is made to power the park lamps when the headlights are on. I would think it would be at the headlight switch, looking at page 8-96 of the manual, a jumper between H and P, but see no mention of any kind. Can you tell me where you found it?
Yes, Not needed or designed back in 65. My 66 Dart is the same. I think all you need is a jumper between terminals to turn the park lights on with the headlights. Let me see if I can find the thread.
