Hi everyone
Just installed back up camera on my T@B. I'm trying to locate the wire that will be my power source. So I open the LED light on the driver side above the speaker, I found the wire that power the LED they are colored white and blue, My question is which one is posotive and which is negative? Thanks in advance.

I'm pretty sure on mine the 12V+ to the lights is provided by a blue wire from the converter. In addition, the 12V- wires are usually white. No promises that yours are the same.
