Turn the headlights on and wiggle the bulkhead connector, Dadsbee probably nailed it....
I tapped and jiggled but didn't get too aggressive or look super close. I'll check again.

Unplugging the Bukhead connector means no power goes in so it can't come out.... If the lights don't come on or at least flicker when wiggling the bulkhead connector the problem isn't there.. Move along.... Try cycling the floor dimmer switch 5-6 times again head lights on...Wiggled bulkhead. No movement. No power to red wire at headlight. Pulled the bulkhead to check to see if power is coming from the terminal where the red wire connects.
This should tell me if I have power coming through the firewall. Yes? If I don't, then I'll start investigating the switches again.

This car is making you earn every inch... Typically wires don't fail in the middle, connections fail, switches fail... Runs of wire unless flexed or chaffed don't fail...Did that many times. Switched lights on and off many times. Power at bulkhead. Power at weatherpack. Worried that other half of weatherpack was bad, so pulled the plugs apart and connected wires directly. I replaced both ground wire terminals in case they were bad/loose/etc. Still no lights and I can't seem to get a power reading at either plug (low and high beam) on the driver's side with the foot switch in both positions. Maybe a broken wire between the weatherpak and headlights.
Service manual says the problem is in the switches.
Gonna take another break for a day or two LOL.
Thanks again for the advice, everyone. I'll keep at it.

Just noticed your five pin connector... That's not OE/stock so that adds to the excitement... Actually on a Charger there is a OE connector with five wires on the headlight side... But it's rectangular and has six wires on the body side....
Oh, nice touch with the VW battery... Just keeps it fun, end of the day none of that matters, gotta get 12v from the floor dimmer to the headlights....
So, probe for power at the floor dimmer switch.... two out of three should be hot, the one that's not will be after you cycle the dimmer switch...
Originally Purple is high beam, red is low beam... Black is ground... Purple & red should pass through the bulk head connector side by side...
And now that I've looked at a schematic the power from the battery is on a different plug so you can unplug the headlight harness to probe if it helps you...
Do you have any spare headlights you could plug in... Wouldn't be the first time two headlights up and failed....It sure is LOL.
The OEM connector disintegrated in my hands. Making a new connector seemed to make the most sense. So, I pinned them all out and connected them with weatherpak since I couldn't find a decent bulkhead-to-headlight harness. Mine only had five wires on either side, though. All colors matched. I am seeing 13.4 volts at those wires, on the harness side.
Red and purple do come through at the bulkhead, yep.
Seeing power at more than one wire makes sense, now that I know one is for low beam and another for high.
Trying to figure out how I have power from the harness and re-did the grounds for the headlights, to the rad support... but still no lights.
The fact that they JUST WORKED GREAT a few days ago just makes it frustrating.
As for the battery, it was free and I'm not spending money to replace stuff that works until I fix stuff that doesn't.

If you want OE style harnesses you want M&H, sold by Year One & Classic Industries....
Someone's been getting "creative"
yearone discount code,today only HEART24Seems they were. Lol
Pics of the bulkhead and plug in question. Both the purple and black-with-green-stripe wire locations have power when the light switches on. Last picture 8s also the plug-in question, I noticed when I plugged it in a couple of the wires seem to pop out from the back, a bit
Aaaaand of course they both popped out at the same time so I don't know which one went on which slot. Jesus.....lol.:
