Looking for a wiring diagram

I've got a pdf manual for my 08 te450, but the wiring diagrams are too blurry to make out the wiring colors. Does anyone know where I can get a higher quality set of diagrams?

Thanks in advance,

I think you may be SOL. I've heard that some owner's manuals have clear schematics... so maybe try to score one of those too.

Is there any particular wires that you're interested in? blow them up in your pdf viewer and stand back from the screen a bit- sometimes that helps. Rotate the view too.

I didn't think about chasing down an owners manual, will give that a shot. Problem originally started as no brake light, after confirming the switches were working I ended up finding no power coming in. Traced the wire back to where it ties into one of the two power relays, all the proper grounds and power there and the relay tested good. Came back the next day and it's now working. Maybe testing the relay got it to act right? This one has me scratching my head. I appreciate the advice, hopefully it'll be a while before it acts up again lol.
