Got it, thanks for the explanation.

Does your Supplement show this same info that's in the 2017 version?

If not, what does it show?

My supplement is the same but the wires on the truck do not match the supplement. Only two of them are the same. I can grab the other colors tonight.


Did you connect them behind the glove box?

Is there a hookup for the Gen 2's? I was under the impression that this was a gen 1 thing and the Gen 2 wires were already powered under the hood. If I wanted power inside I thought I had to hook it up under the hood.

Yes, that's correct. Looking at the thread I linked to you can see the Aux wires are powered and to bring power into the Cab you'll use the Pass Thru wires and connect one or more of them together under the hood.

I figured it out, the 2018 wire colors are different.

Aux 1 Green/White
Aux 2 Brown/Blue
Aux 3 Gray/Yellow
Aux 4 Green/Yellow
Aux 5 Brown/White
Aux 6 Green/Orange



Also my hot leads were the ones to the drivers side of the truck, buy the ecm wire connectors circled in the pic. From my understanding this is opposite of the 2017's. I will post more info when the install is done.

I wanted to chime in as we just had a 2018 in the shop a couple of minutes ago. The colors have changed but for some reason the 2018 Owners manual has 2017 Colors.
Our engineering team confirmed the following:

2017 Colors:
Aux 1 – Green/Blue - 15A
Aux 2 - Gray/Yellow - 15A
Aux 3 - Violet/Orange - 10A
Aux 4 - Brown/Blue - 10A
Aux 5 - Gray/Orange - 5A
Aux 6 - Yellow/Violet - 5A

2018 Colors
Aux 1 - Green/White - 15A
Aux 2 - Brown/Blue - 15A
Aux 3 - Gray/Yellow - 10A
Aux 4 - Green/Yellow - 10A
Aux 5 - Brown/White - 5A
Aux 6 - Green/Orange - 5A


Sorry about any confusion. These circuits are all active when the truck is running and the switches are ON.

Wonder what the Ford logic was on this change?

Added wire gauge to 2018 aux wires

Going to be wiring up some lights in a few days and I just wanted to verify that these gauges are correct (I was going to put weatherpack terminals on all of them). Isn't the above wiring a bit small (20awg for 15 amps)?

Those are the sizes. The two small wires in each bundle are indeed 24 awg stranded.

I just wired backup lights to Aux 6 yesterday. My Klein Katapult 8-22 awg stripper was not nearly small enough to strip the 24 awg wires. I bought a Klein 22-32 stranded stripper from Home Depot that did the job.

The aux and pass through wires are very short. I extended all six of the aux wires and all six of the pass through wires, by soldering a foot or so of 14 awg to each wire, then used two 6-way Deutsch connectors with pins and sockets.

I used a relay so the little bitty wires from the aux switches are ok, as they are just used as a trigger to the relay.

I'll eventually put some pictures up.

Best of luck with your project.
