n you are all right, is does depend on the make n modles of the neons and the car. howeva, most neon tubes will fit on to any car. basically, it looks more complicated than it is.
youve got 4 tubes, bracket each one in place under the car.... then cums the hardest bit! the wiring! all 4 of the wires need to be runnin up to the engine, where all four of the plugs will need to connect into a box, (which should come with your neons)
this needs to be connnected to the battery and the switch needs to be braking the curcuit!!!
**** not bad goin for a bird a****
