Does anyone know where I can find a wiring diagram for an E450 van. I have 11 shuttle buses that we just purchased and most have electrical issues. Such as no brake lights and no marker lights but all fuses are good. Any help would be appreciated.

 

I'd buy the CD maint manual on ebay if I were you. Did you check the fuses and relays under the hood?

 

Service Manuals, Owner Manuals, Wiring Diagrams, Service Bulletins - Helm Incorporated is the factory authorized seller for the manuals and diagrams if you want the factory ones.

You could also try autozone's site. I don't think it goes beyond 2006 yet, and they don't have 450's that I have seen, but there is the possiblilty a 2005 e350 may have the same wiring colors. It's worth a shot since it's free, and their late model diagrams seem to be just like the factory ones.

To get to the diagrams you have to register, plug in your vehicle(in this case you might have to fudge it and say 2005 e350) and then click on "vehicle repair guides" and then "wiring diagrams".
