You might have to check in the engine compartment on top of the inside fender area.  For example this is where the auxiliary fuse box is for heated seats, it is a small, bakelite type 2 fuse box with a screw down cap on it.  I would guess that the reclining seats have the same type of auxiliary fuse box somewhere in the engine compartment.

Could very well be a single fuse holder by the fuses. Look for your white wires up there.

Also look for the brown ground wire somewhere.

Seems to me each switch should have 2 power and one ground.

Hi Nathan

That would be good. Knowing you have the electric rear seats too. 👍🏼 I am going to do an interior strip so if you haven't the power supply info, i'm hoping I can trace once striped.
I have the adjustable orthopaedic front seats also but missing one of the rear strap buckets. Any ideas where I might find a spare??

Thanks.

I have posted more info from the service manual update on the other electric seat link in the forum.  However,  this is the page with the wiring diagram

Hi Nathan
Thank you for the info and time spent
It is similar to the diagram I drew from the wires i can see and continuity tested but I think I'm still going to have to strip.
I do have a red wire in a separate tube fuse connector in the fuse box 👍🏼

But the wire at the switch's are different colours to your diagram and the left hand switch ( passenger side for RHD( no sure if the diagram is the same for RHD and LHD) has only 3 wires in to the connector not 4 🤷🏼�♂️

I will post update once more info found but once again thank you and rumb for your help.

And have you checked the relay? I mean the relay at the bottom left of the driver's footwell. There are several fixed there.
happy having finally a 6.9 # 7271 in my garage, ...so nice to cruise!
