I have a 2005 Ducato Based Hymer motorhome. Hymer tell me all the base vehicle electrics are Fiat (ie not modified by Hymer). On the dashboard there is a switch for the front fog lights, which illuminates when pressed - but there are no front fog lights fitted, just blanks. I have taken out the plastic blanks and fitted in fog lights. BUT where do I look to find the spur off the loom to wire them up, there isn't an obvious one.
The previous owner who had the vehicle from new, said it never had front foglights.

The 'spurs' for my vehicle were dangling loose behind where the fog lights go.

Apparently you have an active switch for the fog lights in the cab. I did not. See http://www.manins.net.au/motorhome/miscellaneous.html#fog-lights

Thanks very much Peter, I'll have a look tomorrow morning to see if I can find the cables.
