First, I have no direct experience with the later XJSs.
That said, a lot of the relays used on Jags are generic BUT some caution is required. A lot of relays look the same at first glance but operate differently.
Some relays have a built-in diode. These cannot be replaced with a generic substitute. Usually the relays have a small diagram on the case. Look for the diode symbol. And, if you buy a replacement relay with a diode make sure it is pointed in the right direction !
Also look for the pin designations. Most common is 30-85-86-87-87A but Jaguar (and others) often used relays with a different configuration/operation, 30-85-86-87-87. These are often called "dual 87" relays and operate differently.
Some circuits use a 30-85-86-87 relay. In those cases a 30-85-86-87-87A replacement can usually be used, the "87A" terminal simply being left unused.
