thanks titus!
found this on the wiki also:-
This makes a buzzer sound if your lights are on and the ignition is off, it is not affected by open/closed doors! I know this isn't as most peeps would like but it's easy and available!
Also this will only work if you have blade fuses as fitted to late 86ish 'C' reg vans on
This also only works if you have the 99 wiper relay fitted, not the 19 or no intermittent wipers.
Basically what you need is the 292 relay as fitted to late VW Caddys and from what I can see most late 90's Seats.
Taurus: The VW part number for the 292 relay from the caddy van is IOL0951307 and costs £16.07 including VAT
All you have to do is plug it into slot 7
I have put this mod on several vans now without problems.
This is the relay as it fits in the seat/caddy , so you know where to look. It sits out of the fuse box in its own little carrier!
Which is what i am after but should of looked on the wiki first schoolboy error!
