I had a customer whos boss engine truck caught fire on the wiring loom. They replaced the loom but at the moment they do not get any response from the accelerator pedal, the engine starts and runs but as they have no foot pedal response cannot drive it.

I had a look at the main electronic ecu board and found some tracks burnt on it but after repair still no success. Would anyone have any wiring information for this truck?
