Running a dash-cam off reverse cable

Awesome, more dismantling needed then thanks

I'm out at a show at the moment so can't check but I think there may be a reverse feed at the pdc control module under steering wheel but not sure without checking but something in my mind that reverse camera picks up its switched feed from here ??

Didn't see your last post til after I'd finished but picked it up from behind the B pillar cover, all done now thanks

Having just bought myself a new Garmin Sat Nav with inbuilt dash camera,
LINKY (£224)
I’m contemplating the Garmin reversing camera to go with it.
LINKY (@£85)

The rear camera wirelessly connects with the Sat Nav screen but needs a live connection.

Can I simply tap into the reversing light, and if so which colour wire am I looking for please

I’ve been through about 5 of the 10 pages of dash cam threads that search threw up and am getting square eyed, so thanks in advance.

Bumpity bump

It’s light green with a black trace @Oldrat

The one you can see here with tape around it.

 

[Oldrat]

Brilliant, Thank you so much

Just be aware some cameras have issues with it as it’s not a clean supply due to canbus bulb monitoring the voltage fluctuates or spikes or something (I’m not sure) you may need to pick up a clean 12v supply and run it through a relay to camera and use the reverse signal to trigger the relay

Thanks

Should be green/black on pin 2

Do you know which one is ground?

Plain brown

Garmin BC30 camera works fine powered directly from the +ve reversing light feed.

Andy was it the no.2 wire on the back of the light unit? Green n white?

No as I mentioned I picked it up from behind the passenger side upper B pillar trim, Green/Black.

I have fitted a Reversing camera mirror, it works well, coming on whenever reverse gear selected. Power was taken from the 12v feed to the offside reverse lamp . One problem though, the image shuts down if either indicators or hazard lights used when reversing. Any ideas to overcome would be appreciated.

I had a similar problem using reversing light +ve feed for additional lights and WiFi camera feed, it was solved by using a local ground on the D Pillar instead of the tail light ground. Simple enough to test.

The power to the lights is via the BCM. It’s not a clean 12v. The BCM switches the lights by using PWM. Use the light feed to switch a relay and use the relay to switch a constant 12v supply to your camera.

Thanks,but please can you explain the Acronyms BCM and PWM.

Thanks,I will try that.
