Hello , I really need some help with this before I start guessing and fry something lol

I purchased a 2019 Ford expedition XLT with a fire damage on the dash driver side I replaced the main body harness driver door harness parts from dealer

The dashboard I purchased from a salvage yard it looks like it came off of a 2018 expedition and the harness is just a little different it has a 360 camera module , my original dash did not come with those two plugs and module
unfortunately my rearview camera would show up a blue screen if I don’t have the(just one connecter needed) 20 pin connector connected to that module

But if I have that connector connected it’ll show a half screen rear view and the rest will show all blue screen the other connector doesn’t do anything, also on the screen that shows my driver door is open which leads me to believe why My vehicle says Driver door open when it’s actually closed



Doesn’t say door is open

Says door is open

I was thinking to find a way to connect these wires on these two leftover harnesses somehow if there’s a way if they’re connected just my rearview camera would work and the door open issue would go away

 

What was the extent of the fire damage?
I ask this for a few reasons,
If a lot of wiring was involved, you should get a wiring diagram and check to see what sections are/were protected by fuses or fusible links which could be open at this point.

If some wiring that is not easily seen can make contact where it should not, you could have a repeat performance which we don't want.

Again depending on the extent of the damage, best to be sure before applying power to the wrong places.

 

This is the fire damage

This is my old dash harness

This is the new one that came on the dash off of a expedition with options my vehicle isn’t equipped with

90% sure the fire was caused from this aftermarket wire for screens in the back seat that was done so wrong




I’m 90% sure if I put the right dash harness the camera issue will go away
but a little less sure about the door being open issue
I swapped the door module and issue didn’t go away
honestly the only thing left is the dash harness , nothing else I even checked the door switch if it sent a signal on the wire if I shut the door and it did so I don’t think it’s the switch on the door jam. Another reason why it leaves me to believe the dash harness has something to do with it is because it sends a signal to the camera that the doors open,

my question is if there’s a way to rewire the wire harness JL1T 14401 BCG to JL1T 14401 ATL
PLEASE it would save me a lot of time and money
also I’m

 

Are those wires running along the door sill all cut and not connected to anything, it does seem that way from the picture?

If that is the case , could be why we are not getting the right info regarding the door concern.
