ThugFordEdge3.5 Posted October 7, 2020 Report Share Posted October 7, 2020 I have a 2017 Ford Edge Titanium AWD 3.5L V6. I was looking around under the hood the other day, and I noticed right between the battery, and the metal frame this 3 inch taped up wire with connector harness plugged in to another wire harness connector. It also is held in place by a push in type clip that holds it neatly in place. I've been able to find a picture of another edge. Not even the 3.5l V6 and I could see the plastic harness, but I couldn't make out anything else from the picture. So this wire seems common enough, and I was hoping someone will know what it connects to. I'll add pictures below. Also I should mention I had the rear main seal replaced a few months ago, and transmission was removed for this. So it could very well be some sensor connecting to the transmission, or one of the sensors around the drivers side of the engine. Any help would be greatly appreciated. Thank you.

Just strange to have wire not connected, but also no codes from it. I would think something would have been noticable by now. I do have the engine taking a long time to warm up when it's cold and winter, and this symptom goes away in the summer. So I've ordered a motorcraft coolant temperature sensor, Stant SuperStat Thermostat with gasket. Also ordered motorcraft cylinder head temperature sensor. I got intake manifold gasket already for when I remove the intake manifold. The coolant temperature sensor is faulty for sure. Just the other day I noticed this sediment at the bottom of the degas bottle, and I ended up flushing the coolant, but there is still some in there. So I plan on draining the coolant and removing all the parts and leaving thermostat out and going nuts on flushing using zerex super radiator cleaner, and then I'll use Thermocure and flush using hose for a while before running 80 liters of distilled water. I'm hoping to take care of this issue that's been around for 9 months. I went to 3 different Ford dealerships, and they couldn't come up with anything. I bought a diagnostic scanner and found the faulty coolant temperature sensor, and right after I found the coolant system full of sediments that is dry like chalk when I rub between fingers. Now I'm just hoping to figure out what that wire is. After all this I'm never bringing my vehicle to a Ford dealership again. I been chasing problems for 15 months. New one with each visit to Ford lol. Edited October 7, 2020 by ThugFordEdge3.5 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 7, 2020 Report Share Posted October 7, 2020 I don't have wiring diagrams for gen 2 on hand, otherwise i would have made a reasonably educated guess lol. You would do well to either buy the manual (paper or DVD), or get an online subscription from the numerous established services such as Chilton's/Alldata/Mitchell etc. The online sub will keep you current on bulletins Ford puts out as long as you have the subscription. Sometimes discounts are available, check around for coupons such as on retailmenot.com. The sediment is most likely coolant additives fallen out of suspension, but that is never good. Means the coolant was run too long. Either use an aftermarket (non-orange) extended life coolant or the new Motorcraft Yellow. Just my 2 cents. The cleaner is a good idea, hopefully only needs 1 pass to work. Don't want clogs in the radiator or heater core. Quote Link to comment Share on other sites More sharing options...

I think the whole situation got much more serious when I reached back there and all the wires in that taped up area are cut. I been getting some strange behavior from one of the dealerships. I called and spoke to manager about the vehicle taking a long time to warm up, and that was a month ago. Before finding these wires I felt like they where afraid to deal with my vehicle or go near it. It's been 30 days of excuses and told this and that. Also they where the ones who replaced my rear main seal. So I think those wires may have something to do with it. Somehow I'm not getting any Codes from it, so if these wires are important. Then whoever did the cutting, did it intentionally because they also did something else to block these codes. I'm hoping I'm wrong, but I don't think 3 to 5 wires just randomly go in Ford edges and connect to nothing lol Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 9, 2020 Report Share Posted October 9, 2020 You have to get your hands on the wiring diagrams. Quote Link to comment Share on other sites More sharing options...
omar302 Posted October 9, 2020 Report Share Posted October 9, 2020 I just checked my 2016 Edge Sport, and it is the same. Actually the wires are not cut, but are a plug, they turn around to close a circuit, probably it is for something out Edges are not equipped with. The only thing that comes to mind is the Auto Start-Stop that I think is only equipped in FWD 2.0 Edges in 2015-2018 models. 1 Quote Link to comment Share on other sites More sharing options...
dajo2012 Posted October 9, 2020 Report Share Posted October 9, 2020 Just for the heck of it I checked my 2020 ST. It has exactly the same plug and wires. 1 Quote Link to comment Share on other sites More sharing options...

I'm assuming it may be a junction connector. Or at least that's what I found on another forum discussing that wire. I had gotten the code on that black plastic harness 33472-0723 And then did a Google search, and only one discussion about the wire came up, along with the actual harness connector plug for sale at a few sites. Here is the link to a Ford fusion forum that discussed this exact wire plug http://www.2gfusions.net/showthread.php?tid=9060&pid=145646 2 Quote Link to comment Share on other sites More sharing options...
omar302 Posted September 6, 2022 Report Share Posted September 6, 2022 I know this is an old thread, but read a similar finding on the Fusion Sport forums (2.7 EcoBoost - link) and they refer to it as a dyno plug, unplugging it shuts the traction and stability control off.
