Ah thats really frustrating sorry it didnt work
Reverse Camera and LED Tail Light conflict

Yes its a pain as I only ordered these lights as they were meant to be plug & plug. I've emailed THQ so keys see what they come back with.
Where is your camera power taken from? The reverse feed or new feed from the fuseboard?
Hi , I have a 12v feed from the fuse box going to 87 on the relay. There is also a blue wire spliced into the reverse wire & that goes into 85 on the relay.
I was very careful and double check i put the connectors on the right numbers

Or keep it handy and change your complete BCM coding from : E0A4303A0A212031002009742E2B9C500F00708F60464DE0320400220800 to E0A4303A0A212031002009642E2B9C500F00708F60464DE0320400220800
Could i
Hi Robert , thanks for the link. It does not mean much to me with my limited electrical knowledge. The camera was not fit by me but it has worked spot on until I installed the LED lights yesterday. I have done a rough sketch of how it looks to be currently wired, do you see anything wrong with this ?Reverse signal for dashcam rear view

Whats happening at the block? Are they all joined together there?
The block is sealed hard plastic & several wires for the monitor are all joined inside. Like I said previously everything has worked fine for 3 years but for whatever reason these THQ led's dont like it.
Hi Deaky , I have the same situation with my new THQ rear lights, this is how my aftermarket camera is wired ( it has worked perfectly for over 3 years ), can you see an issue with the wiring now I am on LED lights rather than halogen ? many thanks
Difficult to tell without knowing what the wires are for. I cant see a -ve connection for the camera. So the 'box' has a permanent +ve and a switched +ve from the reverse light? Have you verified that the relay is closing ok and not chattering? Maybe you need to code the rear lights to LED?
the relay should be ok as its brand new, I only bought it on sunday as another forum member has said this certain relay solved his problems. My electrical skills are basic so I'll have to get an auto electrician to have a look at it.
You should be able to hear the relay 'click' once when you engage reverse, that will tell you if it is switching off the reverse feed correctly. Looking at your wiring diagram above it looks mostly correct but as @Deaky said its hard to verify as its hard to know whats connected at the box and also some of the wires I suspect are the visual feed rather than power.
I could sketch up a diagram of my set up if would be any help?
worth also checking your fuses, to rule that out, as you said it was working fine before.
With the ignition on ( engine turned off ) if i put it into reverse the relay clicks once as expected and the camera works perfect.
If I then turn the engine on & put it into reverse then the relay goes crazy & buzzes & the camera does not work.
if you could do a sketch of yours that would be much appreciated, many thanks.
The camera was fit in 2017 & I've had no issue at all until installed these Led lights so there is something that these lights are not liking.
Sounds like the relay is not doing the job and the remainder of the wiring is working as it should.
I believe that the diode on the relay is directional. Ill sketch it up later after work however in the meantime.
I have terminals 85 and 86 the other way. Therefore mine is:
85 -ve Connection to ground (chassis)
86 + feed from the reverse light (in your case the blue cable)
if your interested some background and further explanation is here: Automotive Relay Guide | 12 Volt Planet
Great link - thanks for that
Hi , i realised my 86 and 85 were the wrong way round after reading about diode direction. Also 30 & 87 were the wrong way round although im not sure that it mattered ?
Unfortunately swapping them round has made no difference and i still have the same issue. I've spoken to an auto electrician this afternoon & he seems to think its a simple fix ( fingers crossed ).
I've attached how it is currently wired.
Hi Mate, update on the lights. Auto Electrician sorted it very easily. He fit a resistor on the switched live from my reverse light. No messing about with VCDS or anything like that. £40 job done, happy days !
Are you sure it was a resistor and not a diode?
