I noticed these are conspicuously missing on my car, it is a dec 91 build 4.0 litre sovereign, australian delivered. Should I actually have these relays, if so what number relays are they??? Thanks. On a bright note, should have the car on the road in a couple of days after I bought it june 2013.....slow but sure...

 

Relays are itemized per model year in the back of Haynes, and AFAIK your year doesn't have them (or quite a few others) - still, the 91 is designed to function just fine on what relays it does have!

You can check the parts diagrams at jaguarclassicparts.com. It's possible your car was not equipped with secondary air injection or a breather heater. I don't think all markets received every emissions-related add-on.

 

The breather heater was to prevent the icing of condensation during PCV flow. It could be that this wasn't necessary in your climate.

 

Thanks gents!!
