Front headlights wiring?

[paintman161]

Had to take the headlights off the Ford 1900 since i have the bottom of the hood repaired and put in a new grill. But for the life of me i cannot remember how it was wired together. Also i am pretty sure these are new headlights from TSC. I am attaching a drawing of what i have at the moment, the previous owner had cut the white and black wire and tied the red into the lights, but i forgot how it was all wired. Anyone have any ideas please?

I have a 1900 and just looked at the wiring. The black wire runs to the ground underneath the radiator and to both headlights. The headlights are two wire bulbs so one of them must be high beam and the other must be low beam. The one on the right had the red connected to it and the one on the left the other color. You should be able to see this function when you turn on the headlight switch and measure the voltage. There is only two wires that come out of the harness near the alternator that go to the connector with the 3rd wire being the ground to the headlights.

Black should be grounds. Check the other 2 with a multi meter.
Would think low first from the switch.
Now telling the difference in hi and low beam probably would have to happen at night.
