I installed a backup camera to my 03 Liberty and it works, except that it triggers when I press the brake pedal rather than reverse as it should. So I know I have spliced into the wrong wire in the tail light after reading some wrong information on the internet about the colour to use. So rather than get it wrong again does someone know 100% which colours in the tail light I should splice my positive wire into instead? I attach the wire diagram I found later and it looks to me like BR/LG would be the one? - Brown/Light Green? If someone can confirm that would be great. Photos of the are installation attached. It is very close to being finished!
