After the engine-out job (to fix the myriad oil leaks) all the wiring harness clips are missing. (They told me they were so brittle they all broke up. Hmmm.)
Are these affordable from the dealer, or is there a better way? I don't much like how it looks with tiewraps everywhere.

 

I suppose you can get them from Nissan. I have not found them or anything similar in auto parts stores. I use small black wire tires and make sure I clip the ends. They look neat and tidy to me.

 

You will have to replace the entire wire harness. I recomend the wire tyes.
