Hi Matt,
Seems my rads' a bit oddball - switch pointing forward not aft, think I've worked out the three connections thing, seems existing switch is odball too. Three wires from out of switch - earth separate!! Anyways, the replacement (ebay) has three wires via two connections - it has to do the same things so I guess we'll work it out. It's OE standard (Valeo) so should revert back to standard.

Regards,
Tony.
