Looks like two of the connectors needs to be swapped:

Roland,
How is the wiring different? The H4 lamps use the same connectors as
the stock ones with three wires--high, low, and ground? I agree the
source for the wires should be changed to use relays, but the actual
connections are the same? And I assume for the LED lights too?

Chuck,
All Panteras use the same headlight wiring. I don't know what your
car's problem was, but I think it was your car's problem.....

One caveat about the seductive lure of simple plug-in LED
bulbs for Panteras: Not all of the LED bulbs will work in all of

David is part of the MidAmerica Pantera Squadron here and
his success with the simple installation of the LED bulbs persuaded
me to try them on my late 74 Pantera VIN 7191. The first pre-dawn
back road trip they worked great and then.....they worked, but the
output was much lower. Another member of the Squadron who is much

I noted that David's Pantera is VIN 3659, while mine was
7191. It occurred to me after thirty plus years of Panteras, that
there may well be some difference in the wiring harnesses over the
production run.
We tried an experiment with an early pre-L with a VIN less
than 2000. The LED bulbs immediately worked as advertised. These
are the same LED bulbs as David used. Apparently, the LED bulbs
that David uses seem to work much better in earlier than later
Panteras.
My advice given the gremlins in the Italian wiring is to
obtain some guarantee from the vendor for a return and refund if
they don't work properly. Good luck and if anybody has had a
successful LED installation in a Late '74, then please let me know
the specifics.
Warmest regards, Chuck Engles
