Hello,
I have a 1990 Landcruiser UTE and the headlight connectors have been cut off. Can someone please tell me which wire goes where on the sealed beam?
Regards Col.

Toyota used several different systems for headlights.
Is one of the wires white with a black trace if so this will be an earth wire and should go to the left parallel terminal with the un parallel terminal at the top.
If there is no white/black wire it could have a common positive. Seperate the wires and find the wire with 12 volts with the lights turned on and should stay 12 volts on both hi and lo beam, this will be the wire for the common LH terminal.
With the correct wire on the common terminal trial and error wont tahe long with the other 2.

Sort of related to same above
Toyota use one wire as 12v supply to the common terminal of a twin filament globe supply, and then earths to negative the exiting power leaving the headlight. So the combination switch/headlight stalk, switches the power from the headlight to earth/neg through the switch. One is high beam related and one is of course low beam.
Reverse to what Holden used to use.
Therefore, with the TOYOTA, two of the wires will, one at a time, be earthed by the hi Low Switch and one will be ON whenever the stalk switch is turn to ON. ie the supply to the headlight.

Col, hope you have sorted it out. i can tell you sealed beam lights have a different pin orientation to hallogen globes. Toyota have a positive feed when lights are switched on, and the column stalk switches negitive
