Hi my name is ***** ***** I will be the expert working with you today to help resolve your problem.
you do not need a wiring diagram all you will need is a pair of RCA audio cable which has both ends red and white connectors
connect the red one to the red port on the back of the sound bar and the white connector to the white port and then the other end of cable gets connected to the audio port of the poloroid tvs audio port which has the same color red and white
i am attaching a video which will help you get connected.
let me know if you have any question.
check this link the audio port must be like this http://tinyurl.com/luq6agp
the back of the sound bar is not as shown. Among the other illustrations there is one shown with two aux ports marked 1 and 2 There is an optical port, DC port and a co-axial port. The T V has no optical port and has jack ports not marked?
can you tell me the model number of the soundbar
