The wiring looms for XJ40s were mostly one size fits all
, and included wiring for options that might not feature on your car.
You know whether your car was originally fitted with front fogs if you have the corresponding switch on the LH side of your dash...
If you want to retrofit them, you will need the fog lights (purely ornamental with halogen bulbs, they melt as quickly as an ice cream in the Sahara
) and the dashboard switch to get everything to work.
I did that upgrade on my Sovereign a while ago:
Before: blanking plate instead of switch
Blanking plate removed: note the 'on' indication LED is present already!
Donor PCB, showing the switch layout including front fogs. I cleaned the plastic switch and fitted that onto the PCB shown in the previous pics.
