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?
Had to go to my outside garage to have a look see. I didn't see any reference to the connection in the factory wiring diagram in the shop manual, but the laminated full color extra large diagram I got off ebay shows the connection.
