Sealed beam question

Is this what you need?

As for the actual pinout, I don't know. I can check the '83 in the garage
this weekend. It has the above harness for the H4s.

Check continuity with an Ohm meter. Find the two pins with the highest
reading. The 3rd pin will be your ground.

For high/low, well, if you have a 55/60 bulb, then you ought to have
different Ohms reading from the ground to either pins.

55W pin should be the one with the highest reading of them both. At 12V, the
highest resistance (Ohms) filament will flow less curent, hence less Watts.
And vice-versa. But I suspect you will need a very precise Ohm meter to
mesure it.

Cheers.
