Could probably hook them stright off the battery then and have a switch in the cabin to turn them on? Depends when you want them to run. If you want them to be with IGN then you will have to trace down a suitable wire, if you just want to switch them yourself, then chase a wire from the battery, to the lights and then back to the battery, but then rather than attach it to the -'ve, poke it through the bulkhead (there is a rubber grommit by the batt). That comes out in the passenger footwell, so chase it over to the drivers side and attatch a switch. Earth it and jobs a good un. Make sure that the wire to the lights is fused right by the battery though to ensure if it goes wrong it doesnt kill it
