2016 Ford Edge

Recommended Posts

Has anyone used a cut off switch so you don't have to take the negative battery cable off a 2016 Ford Edge?

Any concerns with doing it this way?

Anyone have any kind of concerns towing all wheels down with the 2016 Ford Edge?

I have a 2016 Edge and had my Ford dealer install a Blue Sea 500Amp cutoff switch on the negative terminal.  On Page 234 of my Owners Manual, in the Towing Section, Step 4 for Keyless entry has you disconnecting the battery.   Be very careful how you do this as there are three ground points off the negative battery cable.  The one on the fender well stud, for jump starting, one on the engine, and one goes to the electronics.  All in a single piece bundled wiring harness.  This is not for the faint hearted to trace, I worked with my local Ford dealer for several hours figuring this one out!

Now for the "gotcha"...  If you disconnect the battery you obviously kill the factory power outlets you need for your brake system and in my case tail lights.  To power the Blue Ox Patriot system and the TowMate 32" Wireless Brake and Tail lights we use I ran 12VDC from the coach 7 pin connector in to the Edge.  I then connected that to two power outlets I installed under the dash that allow the Patriot and TowMate to plug in to them.   

My Edge has all LED lights in the rear.  I wasn't willing to modify them as I know from a previous Ford just how expensive those LED light modules are...  So that is why I went with the TowMate wifi system.  The gotcha here is the whole rear of my Edge is either glass or plastic on the horizontal flat areas.  I used an old hitch with a piece of 2X2 inch tube welded to it to mount my lights.  

The way my Edge is wired now the only mod to the factory wiring is the Blue Sea cutoff.  Everything else is wired on easily removable two wire pre-made cables made to be used with a Deltran Battery Tender.  If you want more details and the Part Numbers let me know...

One other "gotcha":  I highly advise you to have a couple regular keys made for the drivers door as the "key" in the fob is next to useless.

FWIW:  I could not get an official answer from Ford on why you need to disconnect the battery.  Prior to 2016 it wasn't in the Owners Manual.  What I was unofficially told is too many folks were killing their Edge's battery due to the toad's auxiliary braking system.  If you leave the battery connected every time your toad brake system depresses the brake pedal it "wakes up" the vehicles electronics as it thinks you are getting ready to start the car by putting your foot on the brake.  And the system stays active for several minutes each time.  The cumulative effect is to kill the battery...  Since I was modifying a brand new Edge I followed Ford's guidelines to the letter.  I don't want any potential warranty claim issues.  That is also why I had my Ford dealer modify the wiring harness instead of a third party.  I freely admit this was overkill on my part...

BTW the Edge tows great!

Regards,

Wayne

Could you simply install a charge line from the coach to the toad to keep the battery charged all the time?  that is what I did to my F150 after running the battery down one night when I left the auxiliary brake connected.

Yes, that would be my preferred solution...  But when I asked about it everyone at Ford followed the Owners Manual "guidance".  Since our Edge had less than 500 miles on it when all this was done I followed their directive.  For the $200 for the battery disconnect installation it wasn't worth worrying about any warranty questions caused by not following Ford's directions.

Another way to handle this is to put in a disconnect, as Ford recommends, and then use an aftermarket fused connection directly to the Edge battery to power the toad brake and lights.  Then you wouldn't even need a charge line.  Just remember to run your engine every evening to recharge the battery.

I have a 2013 Lincoln MKX and it is the same as the Edge in many aspects.  After 4 hours on the road the battery would be dead.  My fix for that until I can get a charge line installed is that every couple hours we stop for stretch and other niceties.  I start the car and let it run for 5 minutes, then off we go again.  Works well for us.

If everyone would do that we wouldn't have manufactures wanting to disconnect the toad battery.  :)

Things change and apparently the Ford 6-Speed Automatic Transmission - 6F50/6F55 has to have the battery disconnected according to the Ford Edge 6-Speed Automatic Transmission - 6F50/6F55 manual.  My bad.  In 2013 the Edge and MKX both had the same requirements and the battery was not mentioned in the manual. 

In my case I don't know why I have to put the key-less ignition into the accessories mode when after 10 minutes everything shuts off. But, that is the way the manual states and that is the way I do it, by the manual.

Yep, to bad they don't standardize it.

I just purchased a 2017 Ford Edge SEL. In reading this thread I noticed that Wayne states, "...Be very careful how you do this as there are three ground points off the negative battery cable.  The one on the fender well stud, for jump starting, one on the engine, and one goes to the electronics.  All in a single piece bundled wiring harness.  This is not for the faint hearted to trace, I worked with my local Ford dealer for several hours figuring this one out!...

A couple of questions:

1. Didn't the dealer just remove the negative wire bundle off the negative terminal and connect that to one side of the cutoff switch and the other side to the negative battery terminal? Or was it more involved that?

2. What effect on electronics  memory does this disconnection have, (i.e,., radio programming, etc.). Or do all of the electronics maintain their memory?

3. Any other gotchas?

BTW: I plan on installing an accessory 12vdc connector directly to the battery for my RVi Brake. Also a 12vdc line from the coach to the battery to keep it charged while towing. I will be using power from the coach to via the six pin connector for the tail lights. This is what I did on our 2013 Ford CMax that we traded in for the Edge.

If anyone else has recommendations/information regarding flat towing the Edge I would like to here those also.

Larry,

1. On our Edge there were multiple ground wires that run to the negative battery terminal.  It wasn't just a quick remove and replace to install the disconnect with a single cable.

2.  Surprisingly we did not have any serious memory loss.  The Trip computer normally reset but the radio and GPS were usually fine. 

3.  Other "gotchas"?  Well I'm not sure if it was directly related to towing but we had serious transmission issues with the Edge.  It developed an issue where it would "clunk", loud and hard,  if you were decelerating and then accelerated again.  This was most noticeable when coasting up to a Red light then accelerating again, on the Green, without coming to a full stop.   Our dealership did software reflashes, module replacements, and fluid changes trying to address the issue.  All of the fixes lasted about a thousand miles or so then our "clunk" returned.  Since it was running up on the 3/36 warranty we traded it in...

We ran a 12VDC feed from the coach to the Edge to supply the power for the braking system and towing lights.  That was a easy way to power everything.  If you are going to do the battery disconnect I wouldn't bother with a charge line.

Happy 2018! I am very glad I found this forum.

I just did a deal on a 2017 Edge 3.5 AWD (today) and would take possession later this week. The intent is to replace the Mercury Mariner AWD Hybrid we have towed for over 45K miles with no issues. 

While I did my research to confirm the ability of the Edge 3.5 to be towed, I totally underestimated the additional complications of having to disconnect the battery each time.  

The last two posts covered many of my questions. Before I decide if I am canceling the deal I want to confirm a few things.

1. Can you avoid the battery disconnect with charging line. If so what are the down sides... warranty?

2. Is it necessary to use a supplemental taillight system?

As Larry stated, any other help or recommendations are welcome and greatly appreciated.

I have a 2017 Ford Edge  SEL  that I am starting to get all the necessary parts for flat towing  base plate bx2657 and just a week or so Blue Ox finally came out with a wiring kit for the tail lights bx88334   I am planning on disconnecting the battery and running a wire from the RV to the car battery as well.  I will also install a 12v plug in the car that will be connected to the car battery at all times.  If you try to run your brake form the rv battery and your hitch fails the brake away switch may not work due to the loss of power.
