Howdy Folks, first post, first Ford truck and already I need help.

I just bought a 1986 F250 with the 6.9L Diesel and 4 sp (T19?). It has wiring issues and I need a good circuit diagram of the engine and starting systems.

If anyone could post a link or something it would be very much appreciated.

Cheers,
Matt.

 

Never mind, got it figured out.

 

Here's something I found at a different site. I'd post it, except I don't know how to upload an image, and I lost track of where I screen-captured it.

 

What was the issue and do you have a wiring diagram

 

Do yourself a favor, get the factory Ford schematic... makes life easier when chasing wiring issues. Yes they are pricey but extremely detailed. Here’s a link for your truck...
