Here's yet another charming quirk of ye olde Jaguars.
The Central Locking solenoids are *Hidden* inside the cross member under the back seat. Pull up the carpets and sound deadening to find a panel covering a hole, inside of which are the Locking and Unlocking solenoids.

solenoids hidden here or relays? never come across this before. the crossing over of wires and the empty sp[ades on the button bemusing, but will explore.

 

Mercans seem to use these terms interchangeably. You can see by the photos what these are.
As Steve Yarpos has commented, "People separated by a common language."

When you enter the domain of a specialised technical lexicon nothing is easy and little seems common, I think my speech centres were wired by Lucas Lord of Darkness himself at times. I think of relays as switches and solenoids as little motors. I found them on one side (RIP carpet underlay, rip). is there a set on each side or just one? they look in very good order actually, very shiny.

 

There should be only one pair, attached to each other as in my photos.
Mine are on the Left side, but we drive on the Right side of the road, Left side of the car.
Your world is upside down to us, it may be mirror imaged too as you are almost exactly Opposite us on the planet.

It mostly all makes sense now, however I think I am a wire short. The Blue/Brown that travels with power from thermal breaker (on dash) to the console (I have labelled this wire '9' for my reference). but have the two brown-blue linked appears to be a loop which connects the breaker at dash to the relays at back... this excludes a connection to the switch which is fairly important. i must be missing a wire some place......



wires from Dash to the Console photo'd at the console area. brown-blue with blue '9' tag on it.

the BUTTON .. these wires come out behind the shift stick in a cluster, they include four spades two of which are male and two female and have plastic collars. a blue/brown with no head (marked '9' for my ref) ... this has previous connected to other '9'

button? wires

those pesky relays ... very shiny.

this guy was hiding in the back seat and he had a fatal accident ... paper wasp

 

We are upside down in some regards.

I swear at left in 'picture' is what I have and at right what logic seems to suggest i would need to have for the circuit to work. seems i'd either be minus a supply to the relay or a return from the rely to the switch on the console...?'

a diagram of the breaker, relays and switch beneath console ....

 

Well, Yes because if that's what you have, there's no power to the relays, which power Must come through the breaker. That's the whole idea of the breaker in the first place. Brown with various tracers is indeed the power wire.

I can't imagine anyone removing a wire from the under-seat relay, it's probably cut/unplugged somewhere in the area of the shifter.

If it works to reconnect this, you will have successfully conquered yet another "issue." I hope so.

I kinds thionk of the larger ones, as the ones fopund on a starter motor, as solenoids and the smaller ones as the one that energizes the solenoid as a relay.

They have always fascinated me. that goes way back when i bought a device to make the lights on my 37 Ford brighter...

The rely you have identified as the unlocking relay (orange/red) has dual brown/bue wires as input while the locking relay has only a single blue-brown. Is this of importance or am I in fact looking at a daisy-chain of the same wire being looped across from the unlocking to the locking relay? in which case there certainly is no sign of a original wire from the breaker@dash to the relays.

 

the 6 pin plug at the rear of console which snakes its way to the relays is quirky too. a 4 pin plug with corresponding coloured wired connects to it to go to the rely. the remaining 2 pins are filled by the 2 pin plug with orange/green and orange/red wires which have no continuity with the relays and which at the other end snake forward to the driver's side of the shift stick where they terminate in two dead end wires virtually beside the window relay area. what is more odd is that they appear to have continuity with each other and thus are just a loop if connected ... which is pointless even for Lucas. they can be seen in some of my pictures above.

the brown-blue to the relays is in fact a daisy-chain to the second relay. so no power cable from breaker at all...



or if you pull out the switch cluster and the lock relay ...... looks like this ...

 

Actually it only just dawned on me now while looking at the 'Central Locking Successful Repair' thread yet again that the pictures don't show an additional power line to the relays of course because an 'always hot' line to the relays would cause havoc. the single brown-blue i have is intended as in LnrB's image (included here) to go to the switch so activation of such can provide a feed to the relays. I was thinking at cross purpose beneath the cross beam members I suspect. this would make sense (yet to test) and not Lucas's fault for once.
