Tail light schematic 2013 135i

Sthomson77 · 02-12-2016, 08:12 PM

I am trying to find a 12-volt signal from the backup light on my 2013 135i convertible. I need 12-volts to power a Garmin camera transmitter but I can only find 10-volts at the lamp assembly.
Can anyone provide the wire colors for backup light power and ground?

Thanks in advance,

Steve

The backup lights in a 2013 BMW 135i use pulsed (digital) power. This does not work with the Garmin BC30 backup camera! I had to buy a relay at AutoZone and find a clean analog power supply right off the battery (which is in the trunk anyway).
I included a couple of pictures to show how I wired the relay. Name: IMG_2936.jpg
