Vacuum that area carefully so nothimg falls down an intake!

So I did take a shop vac and carefully removed the debris form the area and cleaned everything real good and repaired the broken wire. installed the new part and the Tahoe is actually running very well. no error codes yet, so may have got both covered from the repairs. I made a simple video to follow. Not a step by step, but just some key take aways for others who are thinking about attempting this project in the future.
