Ford Wiring Schematics

    Does anyone know a quick reference, preferrably an online website, to the light schematics for a 2003 Ford F-350? Also, where I can find a diagram for the fuses underneath the hood. I checked the general fuses in the cab, of which none were blown. My problem is, I think, that my marker lights on my truck don't have power to them right now, because I also lost power to my instrument panel lights, dimmer lights, and a few other lights/ small functions on the truck. This wouldn't be that big of a problem, except that I think this also caused me to lose power to my relays for the plow lights, hence they won't switch over anymore.

    I know the plow lights still work since I bypassed the relays like elite1 said in a different forum, so it must be a power problem to the relay through the brown wire. Any help is much appreciated, Thanks

    I have the Ford factory DVD service manual that covers that year. Head lamp wiring and the power distribution under hood. I will look in and get back to you.
