You have a wanted ad so someone will probably have decent fuseblock and if so, they prob have that connector for the dimmer.
Glad the headlight connector is OK. Mine got a little melted. Even though the lights are now on relays I'd like to replace it.
Did you see the thread about the rear window defroster? There's pictures posted of the heavy duty wiring from the battery and alternator to the ammeter. Something to think about if you're OK with it being a not factory correct for '67.
