Running a dash-cam off reverse cable

11 out of 10 for persistence. I'd have launched it down the road and then got in the van and drove over it for good measure. May have caused me an issue in the long term when I realised that I had to shell out to replace it, but by god would I have felt instantly better in that moment between doing it and when the cost implications set in.
@DaveyB it got close to that but I had already drilled a hole in the rear trim so there was no going back. One thing that is annoying me though is that the camera is upside down. I can't rotate it 180 degrees as I have it set to max tilt. I've seen one on eBay though that's a straight swap and is made for pointing down and outwards but it's £25 which is annoying since I've already paid for a camera that I thought could point this way. Oh well
Dead simple fix. Don't need to be a master in vehicle electronic wizardry and all that hocus pocus. The solution is not to replace the camera. As you've been doing today, take the head unit back out of the dash, only this time turn it over, reinsert. TA DA!
.Ok still having issues with the camera. Managed to rotate it so that it was up the right way but it stopped working today after working fine for a while.
1st try - powered off reverse light live feed - camera switched off after a few seconds
2nd try - powered off reverse camera live trigger behind head unit - worked fine until today and suddenly stopped
I now want to wire it up to a simple ignition live cable. Is there one at the back of the van I can tap into? The loom that runs along the roof front to back is currently exposed if there's one there. Can anyone point me in the right direction?

That would probably be easy enough for me as I already have a new cable running to the back of the head unit just now to the reverse trigger. I could disconnect it there and drop it down to that fuse box.
Any idea what one I would piggy back onto? (To save me a bit of trial and error with the voltmeter)
I think you might find that you will have to fit a relay in any ign or reverse gear supply that you find at the back.
Martyn, can you elaborate on this a bit please. Trying to get my head around it all. I thought I could just take an ignition live from the fuse box direct to my aftermarket camera. Are you saying i may need to have a relay that the camera trigger behind the headunit sets off? Currently on my headunit (kenwood) when I engage reverse the screen changes to the reverse cam input regardless if I have a camera connected or not (as I have the trigger cable connected to the headunit)
No, if you take it from the fuse box it's fine. You only need a relay if picking up at the back of the van.
Subject of relays..
The fuse box live would be the relay supply in.. +
The supply out would go to rev cam +
The trigger would be from your revs switch + or at light the Rev bulb +
The earth would be to chassis -
Would recommend a fused relay, just as ease to find fuse..
But that overkill at the moment, just thought I'd expand on it for others..

I'm struggling to finish the last piece of the jigsaw on my 360 cam, the reverse triggger. I've followed what I've read on many posts about using the green/black cable (I've taken it from the n/s A pillar) but it seems to be +12v constant ign feed and doesn't cut out when taken out of reverse and moving forward. I also tried the light green cable in case it was that but no luck there either. Anyone any ideas what I'm doing wrong?
