Freightliner Coronado Detroit swap

[Corzlot]

I've never needed a computer to fix anything I've worked on, unless it requires a reflash to get things to work again. I have found it is possible to trace everything somewhere. Not that I'm not willing to get one, but it's not my call. I'm not the owner of the truck. And it's not that I've only worked on old equipment. But, with correct diagrams, I can trace down where the faults are.
