So having a no start on 24v that’s driving me insane did a cab swap now truck won’t start blows engine control 2 20 amp fuse on power distribution fuses hooked a test light on it traced back to dash hook up pulled number nine fuse light goes off question is where does 9 10 amp fuse feed and where to start from here

 

Should be a diagram of who does what on the inside of the cover.... If you don't have one, get a service manual for your truck from here. Wiring diagrams and such are in 8W. (fuse block, and power distribution center diagrams are elsewhere though, I think.)

 

They are in 8W. I think 8W-10 & 8W-12
