1960 generator lamp wire for 3 wire alt

[MASTERBrian]

I'm trying to tie into the generator idiot lamp on my 60 burb. I have a diagram for 63, 64 and one that says 60-64. All show the generator lamp has two wires, pink and brown. I'm guessing I'm guessing into brown wire, but here is where it gets odd.

If I ohm the wires to trace it, I get continuity when I seemingly connect the ohm meter to the spot on the harness for the temp light and the back of bulb that's in the generator spot.

My temp isn't a light but a gauge. Any idea here?

The 60-64 all inclusive diagram shows brown wire going to headlight switch AND a label that says '***** dash only'.

I've found the wire in the plug that 'should' be to what I think is generator goes to fuel gauge. I'll worry about fuel gauge later....

Obviously this wiring is a mess, even though some seems to be in original looms. I've also noticed if I ohm the wire that goes to the generator light(brown wire), to the panel, most of those ohm across. It's that ok our not?
