@HOTAS @jweggy You should DM this OP. He has his bed removed. With a 2023 Lariat he should have 9.6 PP.

That’s the million dollar question. We need to see a non-9.6 (7.2) to know what’s there. I’m having my doubts they share the same wiring harnesses.
If the sun visor wiring harness differs between trucks, I bet the inverter harness differs too. The connections will be significantly different.
But it would be nice to compare.
I don’t know anyone at the Rouge Plant.

I have a non-9.6 (7.2) 24 Lariat. Do you think I would need to remove the bed in order to get know for sure? If yes, how hard is it to remove a bed?
@Pioneer74 might be able to help observe a Lightning in production, there must be some running the line sporting only the 2.4KW inverter.

No.. Ive looked into this. Nothing is there that would need to be there. You would have to replace the HV harness in the rear.. Problem is its all sold together and runs from the front. If you can find a used harness off ebay you could take what you need and add it to you HVJB in the rear..
I believe the second inverter is the 7.2 so you have to get the correct one for it to be the right setup. My understanding is you have the 2.4 plus the 7.2 in the lightning where as you only have the 7.2 in the hybrid. So in the hybrid if you have the 2.4 you can upgrade by swapping inverters. Im not fully clear on this point.. but I believe this to be the case.. I am open to be corrected if someone knows for sure.
THere is some wiring you would have to run to the PCM and some linbus. No telling what the programming end would be like.
I looked hard at this.. and could do it. It is a matter of if I feel like it. Dealing with the coolant and HV system isnt very enticing.
End of day its doable just a matter of if you want to deal with it all or not.

The 120/240V AC wiring harness between the inverter(s) and the bed receptacle are identical between the 2.4 and 9.6 kW PP setups. In trucks with the 2.4 KW Pro Power Onboard, the 240V part of the wiring harness is unconnected to the inverter or the receptacle panel. When you replace the part with the receptacles with the one that has the 240V receptacle, you just connect it to the previously unused 240V wiring.I got a somewhat detailed video of the 9.6 Pro Power Plus 7.2 rear inverter hookup detail. If you pause the video you can see the electrical and coolant connections. With the right parts I feel it could be plug and play.
It’s gonna require the inverter, mounting bracket, bolts, 2 wiring harness (inverter in and inverter out/bed receptacle) and coolant hoses. The wiring harnesses could be the big problem if they different between 2.4 and 9.6 trucks.
I think it could be done with spare tire removal and WITHOUT bed removal. Just a guess. The inverter is the smaller component to the rear.
Video to follow when I can figure out how to fit this forum’s size requirements.
It's the HV harness that's the first problem. I was unable to find a different part number for HV wiring harnesses for the 2.4kW and 9.6kW versions, but I frankly found the naming of the different HV wiring harness parts more than a little confusing. Somebody else posting here seems certain there are different versions and I have no reason to question that.
The secondary problem is, if you connected everything correctly, would the software actually let the system work. I have zero clue about that.

Am I looking at a hydraulic piston for a dump-truck conversion???

I looked for different part numbers for the HV wiring harness for the the 2.4kW Pro Power and 9.6 kW Pro Power versions and wasn't able to find them, but I found the identification of the different wiring harness versions quite confusing, so I'm not questioning that there are different versions. Do you have the part numbers for the different HV wiring harnesses?
Edited to add: Here's an HV wiring harness part name:
"Drive Motor Battery Pack Control Module Wiring Harness
dual charger. ELECTRICAL COMPONENTS. HIGH VOLTAGE. PartQualifier: main. single charger. w/o max tow pkg.. w/o twin power. w/twin power. Wire harness."
My understanding of that is that its a HV wiring harness used on trucks with dual chargers that don't have the max tow package, but which maybe have "twin power" (whatever that is), but also may not have "twin power." In other words, I have no idea what trucks its for.
Further edited to add: This is the Electrical "Components, High Voltage" parts diagram I'm looking at:

Its a factory display mock-up chassis, to show what’s under the cargo box (truck bed).

Thanks. I guess that explains why the bed was tilted up instead of being removed like it would be if you were working on it.

i have wondered if it would be possible to simply swap the 2.4 inverter with the 7.2 inverter, and the 240 power panel.
And Just forget about having 9.6 (both).
It may well work, but I’m not sure what would show up on the display

Funny. I had never wondered that until today when I read Jesse-Infotainment's post saying that there were different HV wiring harnesses. Maybe next week I'll pull my bed off and tike pictures of what's under the bed in a truck with the 2.4kW Pro Power. I'd be focusing on unused connectors and any part numbers on HV components.
