Roger, thanks so much for the info, really a great job.
I understand basic stuff so I’ve been comparing your “behind the dash” to mine. My car has the four in line switches, fog, screen, hazard and heater blower (status lamps are above, well they had to do something different for an anniversary car!). Exactly where your new relays sit I have an MFU Box and a Module box, one with a Caerbont sticker.
Presumably on your car the functions are in the box right behind the dials?
Do you know, does anybody know, if this upgrade can be done on earlier cars?
Again, a great job done
