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.
