Hi Brad
Yes! FPR is the Fuel Pressure Regulator.
If the one on 'B' Bank goes on the blink (which they do after so many years) then your Car won't Start.
You can use the one on 'A' Bank as a Fishing Weight, as its totally surplus to requirements.
You might as well have the ECU out of the Boot/Trunk as well (worth as much as £200 even Secondhand)

Brad, your car does have an ECU as Baxtor explained. Pulling the ECUs from the junkyard is a good plan in principle, but they MAY NOT be compatible with your car. The ECUs are different for later cars. But you can keep them and help someone out by advertising them.
You question about the Y shaped pipe between the manifolds: This is the crankcase breather system and it connects to the "pigs snout" black rubber thing with a short spout on it at the front of B bank. If you look carefully this feeds a 16mm pipe that goes into the front edge of the B bank air box. Inside the airbox it connects to the Y pipe and a spring loaded cartridge set in this rubber joiner behind the airbox that leads to the Y pipe. If you want to and are allowed to, you can remove the entire lot, plug the various holes, and run a "to air" breather tube direct from the "pigs snout" down to the subframe and to air.

Hi Brad
Those two FPR's are not the same which is a shame, so if/when your FPR on 'B' Bank packs up, you cannot swap them over.
And while its always better to replace with New, it would get you out of trouble for a while.
Also everything on an XJS is worth money, really serious money as well for some parts and if the Scrap Yard don't know anything about them,
then its better to grab what you can, especially the headlights which are Gold Dust........
I could go on but I'm sure you get the idea.

I don't recall a large electronic box on the R/H side of the trunk. There are two relays and a 2-3" black plastic box with an electrical connection mounted to a rail at the top right near the hinge that sit behind a carpeted trim panel. Then there is an open space and then another trim panel that covers the power antenna. There is a rectangular aluminum box with an electrical connector in the F/R corner of the engine compartment.
Both of these cars were built within 18 months and 14K units of mine. One was built in May 88 and the other in June 88 and neither is a Marelli ignition car so the ECU's may be compatible.
One car has the four headlight arrangement but the plastic chromed housing is gone. The bulbs are still in the car but I don't think they are that hard to replace. The other appears to have had the single headlights but both of them are gone.

Unfortunately both cars have cracked dash pads. One is pretty bad, the other was so small I didn't notice it until yesterday which was the third time I've seen the car. Both cars have resonators but I took mine off. The trunk trim panels are all in good shape. The center consoles as well but both need the "ski slope" wood veneer re-done. Both cars have heated seats. (I wonder if I could add those to my '87?// not sure I'd want to attempt to cut the leather and make a hole in console though for the control button// wiring could be a nightmare as well) I liked the air duct system for the rear seats better than mine so I got that plastic tubing.

Brad, the ECU is tucked up inside the RH buttress, you should find it easily enough on your own car, behind the panel that has all those relays etc fixed to it. You have to remove the carpet/trim to see it. If on the scrapper there is just a huge multiplug lying around and no ECU, then it has already gone. The silver thing in the engine bay is the resistor pack which protects the injector circuit. Not the ECU.
The ECUs will be compatible, grab them, as long as the cars are V12s like yours with the same Lucas or Marelli ignition systems.

As I tried to describe. you are looking for this silver unit. A square part of which you can just see in a rectangular gap in the black panelling just to the right of the RHS buttress's relay cluster. It has the orange label visible with a black square on the label.
The entire unit looks like this:

BTW...I took the cover off the power antenna motor and discovered a bunch of granular like corrosion, light bluish-greenish color, which I suspect is behind why the antenna stopped operating on the junk yard car. It was extended about 18." Hopefully my cleaning of the motor assembly compartment and lubrication of the antenna mast will provide me with a functional spare.

Made another trip to the junk yard today.
Someone beat me to one of the ECU's but I got the other one,. I also got a water temp sensor and the console ventilation plastic tubes. I don't recall my '87 having these but they may work better than the expandable tubing I recall is used on my year.
Too cold to pull the windshield so still no headliner (or two)
AAV on car with engine fire is semi melted on the outside.
AAV on other car would not come off. My Torx screw driver was not long enough to get enough torque to break the bolts free. I soaked them with PB Blaster, hopefully the next time I go back they'll break free.
Decided against the heated seats. Too much work. My focus is getting what I have operating perfectly and to keep my '87 mostly stock original with only a few performance or appearance upgrade modifications.
I did notice that the '89's both had cabin ventilation port flaps mounted in the trunk above the gas tank. The metal frame is held in place with two screws and some black sealant. The flaps move upwards to reveal two holes in the metal panel, each about 1" in diameter. I might try this modification later this spring. Looks pretty easy. Don't know it will make much difference but it might make for a nice Sunday morning project when it warms up.

Hi Brad
This would be worth getting if one of those XJS's has one but your Car and the donor XJS must have the same Steering Column and Same Instrument Stalks etc.
XJS Sports Steering Wheel (See Photo)
Dead easy to remove 2 X Phillips Screws at the back of the Wheel to take the Cover off to get at the Nut.
Then one good bang with the palms of both hands and its off, if you can't do it in 10 minutes then you are not trying.
This Wheel has the most wonderful feel, compared to the earlier type.
The XJS Sports Steering Wheel
2 X Phillips Screws on the Back, take off the Cover, undo the Center Nut, then bang it off the Column from underneath with the Palms of your Hands (Don't lose the Split Collar that will fall out on the floor)

Hi Brad
As soon as you mentioned the Bronze Colored Windshield.
I was thinking that Car must have the 'Sports Steering Wheel' if only I could fit one on my 1990 but in order to do so I would have to change the Steering Column as well.
But my 89 Grey Car has one and I love that Wheel to bits, so definitely worth while getting hold of in more ways than one.
