Need to wirer 3 switches , I have 2 cables into the box 1 has 3 wires , R,W,BLK the outher has 2 wires W,BLK

Several questions. 1. are these wires in a three gang box? 2. what is each switch for? 3. where does the other end of the 3 wire and the 2 wire go to? 4. are all 3 switches in the same location? 5. are these newly installed wires or existing? Without having more info it would be very hard to give you an answer.

1) the 2 cables are in a three gang box . 2) one switch is for light at back door ( inside ) . One for outside light and one for kitchen light. 3) the wiring is coming for the ceiling 4) all 3 switches are in the same ( 3 gang box ). 5) the wiring is existing .

Since it is existing wiring were their switches in the box originally. If so you need to determine which wire is your constant hot. Do all the wires coming from your lights go to your ceiling box?

1) switches are not original . 2) not sure how to determine a constant hot . 3) no way to tell as the cables run up the wall into the attic.
