Hey everyone,

Got the truck listed above that needed new glow plugs for cold starts. Tried to go about doing it myself and I may have crossed the wires for the new plug or plugs that go into the gaskets located under the valve covers. If anyone can help with wiring help and maybe a couple of pointers that would be very helpful. Can’t find anything on Google to help me with this late of a model.

Hello my name is Dave.

As far as the glow plugs go they all are on the same circuit so crossing them wouldn't matter. A common problem with the 7.3 are the valve cover gaskets which contain the wiring harness for both the injectors and the glow plugs, so that is the first suspect. I would recommend replacing the gaskets as a first step however I have attached all the wiring diagrams for the engine in your truck, including the glow plugs and injectors.

Please keep us up to date on your progress and thank you for using 2CarPros!
