Anyone finding a lot of black tape not sticking on the wiring harness on the right side of the engine bay? I found a piece of tape on the driveway and traced it back to the wrapped wiring on the right side. There were other pieces falling off as well, but don't appear to really have been holding anything. I'm wondering if it might be some leftover from the assembly process that isn't needed once the truck it put together.

I've found some here and there, I think it's a case of some poor quality tape. What I've found was fairly brittle, as in it can't handle the hot/cold cycles well and just disintegrates over time. I've re-wrapped some pieces here and there. I had another example of this a couple weeks ago when I was swapping out the blowoff valve, most of the tape on the wires going to the BOV and on the split loom disintegrated. I put new loom on and new tape/zip ties to hold things together better. I predominantly use only some good 3M electrical tape.

I love how I was just looking at a buddies '75 F100 and some of the factory tape is still intact. But these 1-3yr old vehicles its already falling apart. Anyone wonder if that creates more safety hazards, i.e. less protective media on wires? Let's see, a new customer service bulletin soon that tells us not to park indoors again?

yes the small bits of tape that resemble black masking tape are temporary and are used when making the harnesses. i always pick those pieces off the looms when i see them, its not part of the regular harness protection

Thanks, that is what I was thinking since they weren't very robust and didn't seem to really hold anything together. They were very dry and easily pulled off and the rest of the harness seemed to be wrapped pretty well.
