How do you wire up all ride car under lighting up when no colour chart?
You need to create a circuit for the lights under the car, there are two ways to do this. First mount all the lights under the car and then join the wires together in a long line from the first light leave the red wire, connect the black to the red of the next light and so on until all the lights are connected and you have the red wire from the first and the black wire from the last light. Run a power lead from the battery positive terminal to a new on/off switch. Install a 5 amp in-line fuse to this supply. Then run the output from the switch to the red wire of the lights. Run the black wire from the lights to the negative pole of the battery. The other way of doing it i to install a switch to control each light separately. Ja.
