Charles[ Old Goat 67] and I have finally figured it out... maybe a total of 6 hours phone time.... you DO NOT need a jumper wire for the headlights and parking lights to be on at the same time. We believe this applies to the 65 as well as the 66 and 67 headlight switch. And, it could possibly apply to other body styles also. You need to look at your switch and see if terminals 3 and 5 have the factory copper strap connecting them. And please, check your switch in these other body styles and report back here on your findings. This will save everyone looking to do this a lot of headaches from Jack Daniels.

Now on with the show. And first off, make sure your battery is disconnected.

You need to pull the wiring plug off the switch. You'll see a slot next to the terminal to push the wire into the wiring block from the side that plugs onto the switch.Take a stiff piece of wire , or a small screwdriver, slide it up into the slot and pop the Purple wire out of the block. This will collapse the tab that locks the terminal in the block. Pull the Purple wire out from the wiring side of the block. Then pry the lock up so it will lock in the new position. Look at your disconnected switch and you will see the Brown wire is in the #5 slot, which has the copper strap that connects it to the #3 slot which is empty. #3 is where you insert the Purple wire's terminal. Make sure it locks or you'll have no connection.

And viola, you now have the headlights and parking lights connected together so they are both on at the same time. It seems GM had this all set up from the start. Then some dummy said no you can't do it. That's why the jumper was thought of but not needed. So there's no need for scotch locks or a piece of wire for the jumper. And you won't ruin your wiring.

Thank ya Charles, you Old Goat... I love ya man. Charles and his wiring schematics actually made this happen. And without you this wouldn't have happened at all.
