Upfitter Wiring Harness Discussion

I’m certainly interest please post when and where this is available.
 
I just got as BuiltRight email with this in it. This feels like the same idea.

'23 Ford Raptor Fuse Box Mount R&D - BuiltRight Industries

We're finally installing the CB Radio that was originally intended for our F-150 Build! The first step is getting solid power from the truck’s battery to an auxiliary fuse box, we're using a Blue Sea 12 Circuit Block and a circuit breaker mounted in the engine bay. First, Matt 3D scanned the...

This would be handy if you didn't have upfitter switches, but if you have the upfitters, upfitters all are fused and ready to go. It's the hookup that's a problem. Their access leads them to need an extension for easy connections in the future as accessories are added.

I do like the fuse box idea though.

It's a legit pain in the ass. THey are like 4" long on my truck. And there is bad youtube videos out there about where to locate these. Ford coulda done this a little bit better, just bu making these a foot long rather than 3-4 inches.
 
Please include me on your list of customers for one of these harnesses. Do you by chance have a wiring diagram for the 2024 upfitter relay box that shows output wire gauge and color? I can’t find it anywhere on the internet and Ford in their infinite wisdom has decided to not give you an owners manual with the 2024 model year. Instead they expect you to sit in your truck and use the onboard display to pull up a manual file. Means if your filthy dirty from being under the hood or under the truck you have to climb into the cab and reach over to the display to get technical info. Guess it means sitting down and relaxing in the AC with a beer and reading up on my needed info is out of the question. Not to mention what if the battery is dead? Go figure! I’d pay for a printed manual if I could get one. Before you comment I had the dealer send me the e-manual file but guess what you can’t print it unless you go page by page with a screenshot print. If I’m wrong here please tell me. Help!

Try this site. I just downloaded the "owner's manual" in its entirety and as an experiment, printed pages 430-438. (Fuses) It worked. Update: It doesn't show the actual upfitter connections though. Bu5t the harness is labeled. To get the wiring diagram, you may have to purchase that as I did, to get full wiring diagrams.

Can anyone tell me what Ford Publication (page numbers) discusses the trucks upfitter switch system? I just got my 2024 F350 and can’t find much more than a couple paragraphs in the owners Manual that describes the need for the ignition to be on to get supply voltage to the switches. Where can I find wiring diagrams, circuit load capability, wire gauge, harness locations, etc???

The 2024 manual seems to be woefully inadequate on this subject, as you point out. The 2022 manual is not much better but has some designations listed. The fuse sizes are not correct for SW 5 and 6 but it does give more info on the upfitters. (in fact, all of the fuse sizes are listed wrong. See the Body Builders Guide link below.) The wire harness' are not behind the battery tray, rather they are on its side towards the engine. Here's a link for the 2022 owners guide: (The 23 looks the same as the 22)

I also found this body builders guide, it's for 2020 but the upfitters should be the same. Some wire colors may have changed, the 23 and 24 are slightly different when it comes to the PTO, but the Upfitters are the same.
Body Builders Guide from Ford https://www.ford-trucks.com/

Drop down to P123 for upfitters. Location should still be on the passenger side right by the battery. Someone with a 23 or 24 can possibly confirm this.
 
Please add me to your interested list.
Thank you!👍
 
The heatgun trick to pull the weather packing off the end was clutch, which at least saves an inch being snipped off.
 
Happy Friday!

Sorry this took so long to get to. I'm in the middle of delivering the grille lights that I make for the F150 Tremor and had a bunch of traveling in Feb for my day job.

I have a sample for the harness in hand and wanted to share for feedback.

This harness uses metripack 630 series connectors that are rated for 46A. the 6 main circuits are 10ga wire. the 4 additional PTO and B+ circuits are 16ga.

The main harness connectors are the male side of the connection so that the end caps are useable for unused circuits. the pigtails would be included to put on whatever accessory you are hooking up.

I think for production, I'd make the positive legs a little longer to get them more accessible and move the heatshrink on the grounds a little further back to make each connection a little more flexible and independent.

This unit has 3 separate ring terminals for the grounds. for production, they likely would be consolidated to 2 connectors

the production version would use a braided split loom sheathing like I have on the F150 version. the corrugated shown was just what was on hand.

this harness as shown would be sold for $150 + shipping

Let me know your thoughts.

Thank you,

Cory

Sweet! If i didn’t build and installed one for myself already, i would be in line to order. Price is very reasonable too given the materials used.

Essentially, 6 Metripack 2 pin connectors that are 45Amp capable. all 6 grounds would bundle together and terminate in a single ring terminal to ground to the negative terminal of the battery. the positives would each go to the respective upfitter wires.

Not sure if this ended up being the final design but you should not connect to battery ground directly unless you also pass the wire through the CT attached to the frame ground above the right fender.

what does CT stand for? can you explain why not to go directly to the battery ground?

I've always seen "fancier" power distribution setups run a ground from battery ground to a bus bar and tie in all the grounds there. but that's no different than going to the battery directly and adds additional cost for the bus bar.

CT = current transfomer. It measures the current flowing in a wire, and is used by the battery management system to understand the power draw from the battery and its state of charge. If you bypass the CT, the computer doesn't know power is being consumed.
