Just wondering what to disconnect when getting my ecm reflashed for the high idle tsb. I'm not worried about dealer seeing that I have an Edge Juice as my truck is way off of being under warranty. I just don't want their scan tool to screw up my chip. If I just unplug the main harness right at the module will this be ok?

 

They have to unplug your edge to plug in their scan tool so you would have nothing to unplug really.
