If someone could post the Headlight wiring diagram for a 94 Toyota Pickup 2WD. I would be greatful. My high beams work on the drivers side but not the passenger side. I can see all the wires go into the junction box behind the battery. And from there I have no idea.

Both headlights have a full time hot wire. Then the high and low beams are turned on by the grounding side of the connector. One ground for low beam and the other gound is for the high beam. With a test wire I can see 2 wires are grounded with the high beams on for the drivers side. But on the passengers side only one of the 2 wires are grounded. On the passengers side it's the red/yellow wire that's loosing ground and causing the high beam to not come on. But I'm not sure where this red/yellow wire goes to.

 

Have you checked all of your fuses..

I chased my tail on my 90 when I blew one (of several) headlight fuse..

 

I found it...It was a broken wire behind the driver's headlight. Where it makes a connection to the high beam. It was buried in the electrical tape. I cut the tape back to look where the 2 high beam wires meet and found the red/yellow wire was cut.

 

Did you ever get a wiring diagram for 94 Toyota pickup headlights. I have low beams but no high. Indicated light comes on. Replaced really under hood and switch on steering wheel. Found 2 10amp fuses not getting any power at all. Can you help
