Ah who's been reading the Prince of Darkness wiring manual eh???
Just make sure you get the connections right on the light re-adsorbers so that your system recharges at night rather than discharging.
However building those special stainless fire retension walls into the car is a good idea, as they will limit how far any smoke and fire might spread in case of a poor or faulty wiring effort.
I hadn't though about stainless in terms of those benefits, maybe I should get Marty to make me some fire shields.
