Runing a Line output converter on a 2013 RX 350 with premium sound off the subwoofer to a new 350W amp. these wires pictured are coming from the factory amp and they go from 4 wires to eventually 2 wires to the reaer sub. The LOC wants 4 wires so using these but not sure which one is hot or neg? Does anyone happen to know which of these colors are right and left pairs and what is plus and what is negative? It's a 2013 RX350 premium sound (not ML). So far assuming Left + is black, Left - is yellow, Right plus is red, and Right - is white. if anyone knows if this is correct or not let me know? Thanks so much!

The rear #3 subwoofer connectors(O17) and (P22) as per my old 2011 RX350 12 speaker wiring diagram from the service manual. I believe that your connector is the (P22) connector. Per the diagram the yellow and black wires are negative and the white and red wires are positive.
