Thats what you said you was hooking up
You are right I apologize I am wanting to hook all of that up but right now I'm having a diff issue everything else is on order

I only have the backup sensor hooked up to reverse lights when I unplug the passenger side bulb the sensors work with problems

But when I plug the bulb back in it starts beeping uncontrollably

I watched a video a guy said newer cars had light control modules so I fig if I seperate the circuit going to a relay that would get rid of my problem

Then you said my car has trailer light hookups im alittle confused where to even look for this as I can't find any info on the internet about trailer lights


Unless I have them installed please excuse my ignorance

You using the bulb wiring break turn and backup
The camera we used come on when the dodge reverse lights come on.

I got kits that give you lights on the trailer park brake turn and backup the cam used the backup this way you pull no power from the car lighting you could use the switch inside the car but that meant running more wire.

Ok so I found a video on my car


I watched it the cable hooks to my tail lights
However how is that going to send power when I shift the car in reverse ?
 
You might try replacing the back-up lamps with LED's or an LED and a parallel resistor so it mimics closely an incandescent bulb.

You can measure the draw of the new thing and lookup the lamp data for the standard lamp used. Measure the current of the LED or calculate it and size the resistor to draw excess power. e.g. Current (OEM light) ~= than LED current + New back-up gizmo current.

Depending on how the system works, you may have to draw from both lamps, but this does not appear to be the case.

You no it's funny you said that lol I was thinking the same thing

I just now realized the car had camera connection I'm gonna look at it Tomorrow if all else fails then I'll try a lower output light or led with a resistor

You got be kidding me you posted your hooking the camera up to the bulb that comes on when you put car in reverse.

With bulb it don't work without It does.

And you cant see how a kit made to do this works good luck. But most all cameras you buy after market don't power on til the backup lights come on or there on all the time and 90 % of these don't use wiring to send video.

There wireless

The box just gives you more power to run more lights Hope you figure it out LOL.
 
@be80be Backup camera's come on in reverse, otherwise the screen can be doing something like GPS functions. I Just would not expect a large current draw from whatever it is. Power usually comes from elsewhere. Let's hope the backup lights are not powering the camera.

Well The ones we put on the work vans which are wired just as most all dodge are seeing there made by dodge powered the cams from the light wiring where you hookup can do that because it just using the car lights as a signal there power there for aux stuff the kits are made with some transistors that just use maybe a mA to switch on. From what I read you get 3 amps of power.

The cams we have powered on and send video wireless to the dash unit which comes on when the cam powers up in the back of the van.
