Mystery Plug - HELP

I got my Expy ED 5.4 about 3 weeks ago and I really love it…

While under the Expy the other day I found a plug just hanging. It’s a rectangular plug, Two wires. I traced it back to the main harness; it goes into the main harness between the brake booster and the fuse box. Could anyone tell me what this plug goes too??? I have looked around but can’t seem to find where this plug should go…

If its up by the front bumper, then its your oil heater. COld weather item. You can plug this into a wall outlet during really cold night and it will keep your engine oil warm...

I don’t think its the oil heater since it looks like a stock plug to some sensor or something. I did not see the color of the wires, but I will look tomorrow. I found the plug hanging in the wheel well next to the driver’s side running board. I followed the wire to the main harness between the brake booster and fuse box. Thanks for everyone’s help...

I wouldn't go crazy over this. It's impossible for a car manufacturer to custom-design the number of wiring harnesses needed to perfectly address all the powertrain/electrical equipment option combinations possible in any vehicle. Some harnesses have wires with empty plugs as a result. Is everything working?
