No Start/putting back to stock

[russf]

So one of the guys at work here has an 08 f350 6.4L 80000km and it is programmed. He was towing a trailor and the vehicle just quit on him (he said he wasn't on it hard or anything just taking it fairly easy). If we go to try and start it nothing happens i believe (may crank but I don't know for sure). Anyways one of the other guys looked at it and there was an excessive heat code/dtc (not sure which code i didnt look at it). I believe he has an edge programmer but can't say for sure because the guy was tellling me there was a programmer on the dash which makes me believe its edge, but they were trying to set it back to stock to send it to the dealer, anyways when trying to set it back to stock it asks for you to start the vehicle so they're not 100% sure the vehicle is set back to stock as it cannot start. They've tried disconnecting batteries for a while and restarting but that didn't do anything its locked out or something. Does anybody know how to reset this or how to confirm/make the programmer set it back to the stock file? Thanks.

There is a round connector behind the passenger side battery with one wire in it. Disconnect this wire and connect it to the +post on the battery with the key on and it will start. If it will not start the next time you try, then you have a bad EGT sensor in the exhaust.

Thank you very much, worked. For anybody else here is a picture included to show you what the connector looks like (behind pass side battery), Connected the side closest to motor to +positive battery terminal with key on and it cranked/started. I believe its like a secondary solenoid wire to the starter, didn't trace it but thats what it seems like to me.
