Auxiliary wires

Hey guys, I am looking for my auxiliary wires from my uplifter switches. I know they are in the L/H aide engine compartment somewhere but can't locate. I did find some wires by the emergency brake inside the cab but there are like a dozen and a half wires. See the pic.
I will also be looking for the wires in the rear, I think they are supposed to be in the R/H tail light area?
Does anyone have some pics of these locations?
I have a 2015 F-350 6.7 with the factory uplifter switches installed.
Thanks in advance

I have a 2005 so I can not get you a picture, but the wires for the upfitter switches should be behind the dash right there by the e-brake/headlight switch (Presumably just above the wires you have pictured). Again I have a different year but there should be 4 taped up and labeled similar to the pictured. In your truck the relay box for the upfitters goes behind the headlight switch and the aux wires are tapped to the harness coming out of the relay box.

The ones in the engine bay are the pass through wires which should be in the relative same area inside the cab and just behind the fusebox (Apparently down kinda low) right up against the firewall on the outside.

Actually this is the wrong forum for 6.7 trucks for questions like this one. You can find some answers here but many will lbe found on the 6.7 forum that covers trucks from 2011 to current Super Duties.

6.7L Power Stroke Diesel - Ford Truck Enthusiasts Forums


Here is a link to Ford's Bulletin on the Upfitter

2011- 2016 Upfitter Switches Wires - Q117-R2.doc

And the Elevated Idle Control if you want to add it.
