Headlight Wiring

[nfinsness]

I am nearing the end of putting my 1973 "02 back together. I purchased it the way it is. Low beams do not work, but high beams and all other lights work fine. There are three brown (well, brown sheathed) wires leading from firewall toward driver side headlight, all female connectors (2 straight and one 90 degree). There is one male lead near the driver headlight.

Can someone tell me how to connect these properly?

Thanks,

Nat Finsness
