Hi everyone. Long time, no talk.

Been scouring the internet for a 12v switched power on the 2017 super duty.

They conveniently moved the customer access wire bundle to the passenger side kick panel so its way easier to get to but I think the colors have changed.

Anyone know which wire is the 12v switched? Hot with ignition on and not hot with ignition off.

Thanks!

 

Ok. Found some documentation.

There is a green with orange stripe. OUTPUT Run / Start Feed. So it looks like its on if starting or running. It says that its intended for SEIC / PTO use. I don't plan on adding either of those. Think its ok to power my portable nav unit since it seems like just a switched 12v?

Thanks!

 

Not sure if this will help, but just in here's an SVE Bulletin we got on the new PTO's. I don't know how to upload a file guys so I just did the pictures

It also talks about switched and always hot wires. Looks like there is a brown wire under the hood, maybe connect that to one of the pass through wires to get into the cab?

 

screwy, great info, thanks!

 

Thanks for the info. Looks like there is no longer a ignition switched power inside the cab. There used to be.

 

Yeah there is, the Green/Orange cable mentioned on page four of the document above.

It's intended for PTO, but if you're not going to use it for that, looks like it's just a 5A fused switched circuit.

Otherwise, yeah, you can feed an underhood switched source through the pass-thru wires. I'll probably use them for other things.

 

You think that is cool to use? I stated that in my second post but wasn't quite sure. Green/Orange but says it's intended for PTO use. You think its just a simple switched with ignition, voltage? Regardless of intent, sounds like its safe to use, huh?

Thanks man!

 

I would think so. I mean, I'm guessing the intended PTO usage is just as a source voltage for the controller, which is essentially what you'll use it for, electronically. 5 amps is a bit weak, so I wouldn't run anything power hungry off that, but nav units aren't generally power hungry.

 

Green orange worked fine. Its key off/on and not accessory off/on but that is fine.

I got a little bluetooth dongle and mounted it above the fuse box then unhooked the aux in and pulled the aux wire harness down and put the other end of my cord that goes into the bluetooth aux into it and shoved it under the carpet. Looks like nothing is there but now I have bluetooth music!

Thanks for your help identifying this wire.

Pics for fun.




Just a quick connect to the green orange that goes to the bluetooth dongle



Bluetooth dongle wrapped in factory like cloth harness tape and double sided taped to factory box. Used the the bolt on this box as the ground location



Cable going to the now hidden Ford aux in.

 

Sounds like it will be easy to hook up the Elevated Idle control.


Has anyone done this yet?

 

No, was toying with how I wanted to go about it. It looks like it only cares about voltage, they just give you resistor charts to get you close based on typical voltage from the truck. Knowing that, I'm tempted to take one of the arduinos I've got here and see if I can get it to control the SEIC, then I'd be able to punch in a target RPM.

 

While we are on this topic, I was thinking about maybe a 12 volt accessory on the passenger side kick panel fuse box that I could tap into. Something that behaves like the radio. (Stays on with key off until I open the door). That would be ideal.

Anyone have any info on that?

Thanks for all your troubles. I could definately just splice into the power point as they stay on with key off until the door is opened but I told my self I would not cut a single wire on my brand new truck

 

Great keep us updated as im going to do it before cold weather hits myself.. Last truck I just used an adjustable poitemeter or whatever there called and was able to adjust the rpm.

 

Well done Cutter! Except that would be a potentiometer. lol It is a variable resistor.
