Should be pretty easy. For SSD, since the chip is a bridge rectifier of it's own, you can remove the little board full of diodes that's inside the car. Since it's crash-resistant, there's plenty of room for the chip. Also, wiring the chip should be easy since the 360 blade system provides stable contacts to solder to. Just hook the green/yellow wires up front, and the black/red to the motor. Temporarily test the black/red on the motor by holding them on, and making sure the car moves FORWARD when placed on the track and controller. If it goes in reverse, just switch the black/red wires around.
Then, find a convenient place on the centerline to put a hole and glue the LED into. Glue or blue-tack the chip in, and you're done. I prefer hot-glue. Don't use super-glue.
