Hi,
I am looking for a 12v power wire around the radio or fuse box area that I can splice into that switches off with the ignition which I can use to power a wireless reversing camera screen on my 2012 Transporter
I want to hardwire it in and not use the cig lighter socket.
Have tried tapping into the radio power wire but it won't switch off with the ignition and drains the battery
Thanx
