Hello, I am restoring the truck listed above W250 and I am looking for engine bay wiring diagrams and specific wire colors diagrams because I need to repair the wiring harness in multiple locations. Any pictures and PDF downloads would be very helpful.

Yep, here are the engine wiring diagrams that include the engine control module and I have included a guide to help you test the wiring connections as well.
Check out the images (below). Please let us know what happens.

This is helpful, but are these diagrams for a diesel truck? My truck is diesel and I noticed that these diagrams might be for a gas truck. Thanks for the help in advance.

Sorry, they don't show a diesel engine in this truck? Did someone install a different engine?

Okay, thanks this is helpful. Also, if you have one for the main wiring harness that is in the engine bay (which plugs into the cab) that would be awesome.

I also need one that has the light circuit in it because my headlights and blinkers are not working properly.
