that or grab the signal IN wire for the parking/headlights, and have it tie into the IGN circuit instead of the BATT circuit.

Thanks for replies. Like the idea of teeing into the ignition circuit rather than using the battery. This could solve two problems, 1. leaving the lights on, 2. as we drive in Italy and it is obligatory to have lights on day and night, it would then be possible to leave them switched on.

As I do not have a wiring diagram at present, could you please indicate which wires need to be changed (which colour are they?) and where they are located.
Thanks agin for your help.
