Default Weird power issue on Drive side 2002 Jag XJ8

Hey guys, need some help.. Where else would all the driver side seat power be? I have no power on the driver side, I was having the seats redone, so while they were out, I put the driver seat in the passenger side, and it worked fine.. and just to make sure, I put the functioning passenger seat on the drive side it now didnt work. Seats are back from upholstery shop and still facing power issue. I know some of the locations of the fuses. I know they are in the hidden panels behind the front/passenger front seats, in the rear passenger compartment. Question what else should I check and where else might there be fuses specifically to the driver side?Im redoing a bunch of the interior. I have the manual and checked this, but any where else got some ideas? Side note, I did check and see if any power is coming in to harness under seat, I do have power coming in to at least the brown wire... Im just perplexed..swapping seats back and forth and seeing both work on Passenger side tells me the modules are good... and I even swapped those around... man this is killing me, all I have left is this to be able to drive again I added pic of the drive side brown wire on the plug that has power... also the new seat covers, and the correct steering wheels vs the steering wheels someone painted and added a Jag emblem that would hurt if airbag went off

I often get confused with the left/right in hand books. Does it mean looking at car from front or driving seat?
Ether way, there are two healboard fuse boxes. Each has one fuse for seat so as nothing else is working please check both.
Or try and remove the one you have found and see if the working seat stops working or you lose power to the brown wire on the drivers side.

Orientation should be as you sit in drivers seat your left should be car's left

Looking at car from outside front it would be reverse so gets confusing

Each of the fuse boxes has a " king " relay that powers X number of fuses in the box and the rest have power at all times

These fuse # are Y on the earlier inline 6 X300 and would be Z on the X308

You can remove the king relays and feel for them to click in your fingertips back to the open position ( this with the ignition key in run position , engine not started )

Researching

Your Kings relays are :

A
B
C
D
E

reference page 39 of your wiring guide

In this scenario you would have more than one fault with a open king relay , which may not be your case

X300 01/E COVER

The seat modules and seat switchpack each have separate power supplies.
The module is powered through RH heelboard fuse #1 20AMP.

The switchpack is powered through LH heelboard fuse #8 5AMP

You need BOTH fuses to work the seat unless you use the memory, then the switchpack might not be required to power and the #8 fuse can be blown/removed?
Try using the memory or the AUTO feature with the seat movement to allow EXIT.(or just check the #8 LH heelboard fuse)
