Review on 🔌 Enhanced Motorcraft DY876 Glow Plug Switch for Efficient Performance and Reliability by Billy Stull

I installed it on my 2004 F350 Diesel and it fixed the trouble codes I was getting for my glow plugs. Apparently the driver's side often fails, which I didn't know beforehand. Lesson learned: If you're suddenly getting multiple glow plug errors, it could be this switch. It's really easy to install on my F350. It is located on the passenger side valve cover and is held in place by two nuts at 10. Unplug the two connectors and that's it. I am very happy with this item and it was a lot cheaper than local theft in Canada even after currency conversion. Much cheaper!
