Panda 2012+ Rear cam wiring!

[Tim1]

Hi,

I have a Panda 2013 and have wired in a new dash cam. Done the front, then moved onto the rear cam. All wired in except the red lead which I need to wire into the reverse light possitive lead. I think I have identified the loom in the spare tyre place in the boot but there are a few wires there.

My questionis: what colour is the reverse light possitive lead????

Thank you.

Please just use the reverselight current to control a relay. If you draw too much current the wire (thin) will not cope and your lampwarningsystem (CANbus controlled) will throw a tantrum.

Hi.
The reverse lamp is not Canbus monitored as far as I know as when I had a blown bulb nothing came up to inform me on the display.

But it still has very thin wiring.

The wiring may be thin but the camera won't draw much more than 200ma so that won't cause any issues.

Being canbus controlled and being monitored by the bulb failure system are two different things entirely. I wouldn’t assume it’s not controlled by the canbus system.

If it’s part of the dash cam then I presume it needs a constant feed and not just a switched feed

Quick way to tell is to see how much current is flowing through the reverse switch. If its just over an amp it's not but if its milliamps then it is Canbus fed, but I don't really see an issue even if it is as the camera won't draw enough current to cause an issue, you could fit an LED in the reverse light and its actually quite legal.

It will be fed from a switched supply the reverse is a sence lead to tell the microprocessor to switch to rear camera and come to think of it the loading will be far less than 200ma mst likely 10 to 20ma.
Again get the multimeter out and check the current.

WARNING. To check current the leads are in series with the load not across the load (parallel) connecting it wrongly may blow your meter, a fuse in the car or damage electronics.

Why is it switched

If it’s a dash cam it’ll need power all the time to be recording. That’s the point I’m making. Crashes and incidents don’t only happen while in reverse.

I don’t know why you’re telling me to get a multi meter out, it’s not even my car!

 

[murphyv310]

It depends what type of dash cam we are talking about. Some have a screen that doubles as a reverse camera and they need to sense when reverse is engaged like the OP appears to have. For a full time record there is no need to have a reverse sense nor a feed from the reverse light.

I'm aware it's not "your" car.

Having got bogged down in techy detail here, a different approach, and maybe the answer to Tim1 's question? (Which was 'what colour is the wire?')

A bit of lateral thinking finds a wiring digram that shows the colour for the reverse light wiring, and shows it can be accessed behind the trim at the left side of the boot. These are the instructions for fitting a dedicated towbar wiring kit for the 2012-onwards Panda. (In passing, note this is a neat kit that does not take a wire out under the wing and bonnet to the battery, but instead has a custom solution all inside the car at the fuse box)

The wire in the loom for the reversing light is shown (in diagram 14 on page 5) to be grey with a green trace along it. https://www.pfjones.co.uk/pfjoneswiringkits/29050520PF-FIAT-Panda-12.pdf

So grey green is positive
