2005 dodge cummins computer.....
 

I am new to this so excuse me if this sounds stupid but...... Anyway.... I had a guy put his computer to my truck yesterday and he said my truck computer was getting intermedante power faliure and that it might be a bare wire or a dirty ECM? Is it possible to take the truck computer off and clean it? I think I found it loccated next to the battery under the hood. Can I take the harness off and clean it without messing up anything? Any info would be helpful. Thanks everyone!!!
