I pulled the wiring harness off of the sides of the engine compartment (I'm painting it). The wiring harnesses are held in place with plastic ties that have a tab that pushes into the holes in the side of the sheet metal. Once you push the tab in, it spreads so you can't pull it back out. I went to the local AutoZone thinking they would have some. They didn't and they exibited their usual childish behavior, saying "dealer part" and pointing to the door. I'm begining to dislike those guys in there, they never have anything I need. I ended up using regular tie wraps by pushing them in from the bottom, wrapping around the wire, and then back out the hole, but I had to remove the splash guards in the fender wells in order to do this, which turned a 10 minute job into an hour job.
If you don't care about being stock, you can get rubber or plastic covered metal ones that are held down by a screw. They come in different sizes and will last forever.
