anyway to power reverse camera other than reverse lights?

[Jonesjohnson]

i have a skoda suberp 2011 with a newly installed eonon ga6153w i have also a backup camera that have 2 +,- wires, an AV yellow cable and a red cable surrounding it.  

my problem is i cant dirrctly poeer the reverse cam from the rear lights as the fuse is meant only fir them so i brought a relay and connected it, it worked but the relay kept buzzing and i figured that the rear light uses pwm, so now im clueless on what to use, does the stereo have any cable for it? does the shift have any? sensors? help

What do you mean the relay buzzes?

The relay will make a buzzing sound as it's being driven with a PWM signal, causing it to turn on/off many times a second

 

Common fix is a capacitor and diode, a quick google should give you some ideas.

so you suggest using a capasitor and diode is easier than finding another source that lights up with reverse?.  

i am a total begginer in electronics so some help would be amazing

Does it not mention anything in the Eonon instructions? I'm sure my Joying Android head unit had a dedicated wire for the rear cam, as the cable was an RCA and power combined (all I had to in the boot was find an earth)

When I fitted my reversing camera, I fed the power lines to the front of the car and wired it to the fuse box.

 

How about the rear wiper motor power feed instead of the reversing lights
