Need help with Wiring
Hello guys,
I have a 2000 F250 7.3. I am having problems with my headlights. The driver side everything works ie Daylight, Low and High Beams. On the passenger side the only thing that works is the High Beams. I am getting no power to the plug on the passenger side except for the high beams. I have replaced the Headlight switch thinking that was the problem. Still nothing. A buddy suggested that I hard wire the drivers side to the passenger side and well that was a dumb move. Blew the fuses. Now I am thinking that I have a short in the main wiring harness. I have tracked the harness from the headlight switch to the drivers side headlight but then it goes behind everything. Does anyone know if it could be something else? Or can someone walk me through what I need to remove to get to the rest of the Harness.
When I bought the truck in Dec 2017 it had HUD lights on. I switched them back to factory in March 2018 and had no problems with the light till now.
Please help. This is the only vehicle I have and now that winter has set in I need my lights to work.

You may want to forgo the stock wiring all together if you are that far into it. I ran all new 12&14g wire thru relays triggered by the stock wires, stock lights were a touch brighter, leaves plenty of power available to upgrade lights at a later date if you want

X2 on Wesleys' idea of installing a fresh harness. The OE wiring design for the headlights can be improved a lot, that writeup is a good example. If you still have the HID harness you can possibly use that as a model with better wire/relay/fuse. You can probably find a harness on the net but in my experience they use crappy wire, better to build it yourself.
The first time I found FTE I was looking for that kind of wiring diagram for my 75 F250... the one that got away. :/
