If that harness is the expensive part, I will wait until junkyards have more Lightnings and buy for less than $500.

Yea, also, once Lightnings are in junkyards where you can pull your own parts, you can pull the hose connections, the electrical connectors and the Inverter, basically everything you need to install the inverter. I think there is a real gap in the market for salvages to do this kind of thing. Even going as far as packaging/kitting all the pieces needed and selling it as "Pro Power 7.2 upgrade for Lightning"

On eBay right now, if you search for VIN 1FTVW1EL7NWG05344, it looks like it is a parted out Lightning with PPOB. Don't quote me on that, but it looks like it has the wiring harness for $250 and the DC converter for $630.

$1500??? Is the orange color because it's doped with gold, wtf? I get that it's likely low O2 high strand count copper (correct me if I'm wrong here) HV rated, despite most cables I've seen being 600V anyway, that leaves the connectors, maybe $250 in wire, $1250 for connectors? Am I missing something?

Edit: I was seriously considering doing this until I saw this ridiculousness.
The MSRP for a single headlamp assembly is $1,507.63. By comparison, $1.500 for a wiring harness seems cheep. But the need to replace the HV wiring harness largely convinced me to abandon this idea.

Full disclosure: Some Ford dealers will sell you a headlamp assembly for a bit under $1000. What a bargain!

I almost understand the cost of the headlamp, especially considering they include the matrix type lighting. Weird they added it since the primary market disallowed at the time of introduction iirc. I assumed that the 'harness' was just to the inverter, in which case the price is still ludicrous. But if it were to attach at other points then I could see it, I guess...

It's one of several parts of the HV DC wiring harness. I don't think the inverters are the only parts it connects to, but I don't know what else it attaches to.

It is the entire rear DC Harness, with distribution box and all components that touch the DC bus, including the rear drive unit. That's why it's so expensive. This wouldn't be an issue at all if Ford didn't Tier 1 restrict all the connectors with their suppliers. They do this so they can pick and choose which connectors to offer as repair parts, and charge 10-20-and even sometimes 30times the amount it should cost if the supplier sold it on the open market.

Is this rear harness entirely limited to the area under the bed? The idea of replacing a wiring harness gives me visions of what Tesla wanted to do with my Model S to replace one slightly gnawed wire between the HVAC controller and an A/C valve, which would have entailed almost complete disassembly of everything but the body panels, large structural members, and suspension (removals included the 12V battery, propulsion battery, all seats, center console, everything in the dash area, which is a LOT of work, the frunk, etc.) and cost several thousand in labor. I passed on that repair.

If I can replace the rear HV harness with one from a salvage yard once I remove the bed without a lot of hassle disassembling the cabin and dealing with trim that I inevitably make a mess out of, maybe I should put this back on my to-do list, but it'll still have to wait until I'm done with spring work planting in the vegetable garden working on the lawn.

Hopefully you can find one so I can get this done too.

Mostly yes, with the bed removed it can be 100% accessed and swapped easily/quickly. The only part that runs under the cab is the connector that plugs into the front of the battery and runs back to the HV Junction Box.

I haven’t read everyone’s responses, but it seems like getting the home integration system (assuming it works) would be more cost effective and safe.

someone with more electrical knowledge than me could say whether or not that would work. I’m not as read up on the bidirectional power that the lightning can provide on that system. I’d assume that since you can by the integration system with multiple levels of inverters that the truck is just a power bank and input/output would be based on the inverters capacity.
From a value standpoint, I can’t see that adding this would give you any more value resell or otherwise. Adding that capability to your residence should be either deductible or a credit on your taxes at least in the US.
For safety I can’t see that this would be safe for most people to diy, if it was a simple plug and play it would be a different story.

It's a great option, but there are many reasons why people may not want to go this route.

Some non-starters for me are.

I need the power to be mobile. I have multiple houses I stay at as well as my family, we all have generator hookups living in the Midwest.

2nd, 100% of the cost of this mod can be added to the vehicles net worth.

And third, I'm not paying Ford a dime for any subscription services.
