I have a 2008 F350 6.4L and there is a set of wires that runs from the EGR valve and ito the shround on top of the main radiator fan. It then travels down towardas the ground then dissappears. The wires came out of the connector and im not sure what this set of wires do. No engine codes come up when i started it but would like to make sure im dojng an engine damage. Also if someone knows what order the color of wires needs to go back in that would be of great help. Thanks

 

might want to check out the superduty forum, as this is a 2009+ F-150 forum... wish you the best of luck.
