Mystery wire
Guys, baselining a 1997 F250 w the 7.3. Found a small wire with a 90 deg cap on it near the fuel filter. Can anyone identify what it’s for?
I’m uploading a quick video of it here:

Thanks in advance! Clay

Fuel filter restriction switch, (ford calls it a vacuum switch) yours has been removed, it is a leak point and quite expensive for what it is.
also your boot from the driver side valve cover to the turbo (orange boot) is a recalled boot and updated with a black one that doesn't tear as easy foding yout turbo.

Thanks for that answer. Makes total sense now. So should I ask for the updated turbo hose at a Ford Dealership? Mine is torn under the hose clamp on the turbo end. As I detail this new (to us) truck I will probably have additional questions. Another loose wire was found wrapped around the trans x-member - it fit a plug up high on the Driver’s side of the transmission. I’m thinking either reverse light switch or Neutral Safety Switch...??? I hooked it back up, but won’t probably fire it up until sometime tomorrow to see if I have something new working or not haha.
Thanks again.
Thanks again.

I had the same issue with my orange hose. I got the one Riff Raff makes. I had a terrible time getting it to fit on but its high quality.

If it fits that plug, and one of the wires is purple and the other is black, they are for the reverse lights. Go with the Riff Raff turbo hose, the updated one from ford comes as a kit that includes the metal piece that the crankcase breather tube hooks into that you don't really need to replace, but the new turbo hose won't fit the old metal tube. Plus it is a lot cheaper than the Ford kit.
