Bath Bar

As a child of three light bath furniture?
Installation of 3 light bar upstairs bathroom mirror. Each light has three son leaving behind that … black, white, ground. The cables are long enough to meet in the center, where the outlet box. Having more 3 groups outside the junction box .. 2 Twisted Red, idem 2 white, black and 2 ditto. A light switch. How I can son what is it? Thank you.
In this arrangement, the red probably switch cable. But normally, there would be a single thread. Is there any other connected to the light of this change? If so, confirm switching the circuit between the son of two red and see if the other light is not actually light. Best how to check this is to use a test meter, however, if the second fire (or fan) is no longer on and off, then the red is definitely input switch. The red channel will be the hot side of the device bath Triple (three black child). The child must go to all white child to cross the white box. Be sure to connect the son of the mass of the lamp using a Jbox clamp of some sort. If you are unsure how to confirm the source of circuit switching, and you do not have a meter, consult an electrician before connecting anything.
