Hi Folks,
Does anyone know how to pass the wires from a numberplate light camera into the boot? Trying to install the reversing camera on my Brera but unlike the 159 there doesn't seem to be anywhere I can pass the wires through.

It's straightforward on the 159 as there is a big gromit to the right that you can pass the wires through, did it on my last 159, but the breras boot doesn't have this.

I was thinking of fitting one so interested to see how you manage it in the end. Which camera and head unit have you got?

Yes, grommet on the right, need something long if you don't want to take the bumper off, more intrigued on wiring to the reverse light

I passed mine through the ventilator on the o/s r on my 159 must admit, I didn't' see the grommet on mine - it'll be refitted shortly, so will try for it then.

Seems the Brera has a similar ventilator (no.1 on this link) under the bumper, there are small rubber flaps which allow you to pass a wire through, not pretty, but works fine.

Handily next to my ventilator was a pre-made earth point, which simplified things nicely.

My camera was set up with the reverse feed attached to the car's canbus system, so no need to tap a new line - it's either the green or purple wire on the loom - can't remember which.

From what I can see there is no vent or gromit on the Brera where you pass the wire through, if there is can someone kindly take a photo and post it. If all else fails I will be using a step drill in the boot floor to create an opening.

Help with power cables and reverse feed

Hi I was wondering if you could help me with a description of where to get the power for the camera in the boot of the 159 and also the feed for the reverse camera I have the number plate camera installed and the leads through the grommet as you published In another post but dot know where to attach the leads . ...?

Hi

I installed my camera by drilling a bloody great hole through from the boot! I couldn't see how to wriggle the wire to the grommet and I have long since taken the 'destroy it and rebuild it' approach to anything that defies me!!! Because the two big bolts holding the rear plastic cover in place had siezed they too were destroyed..... I have a fine collection of powered cutting tools now.

Anyway, to get the power for the reversing camera I followed the wires from the reversing light into the car and just after the wires emerge from the boot hinge they meet a connector. The connector is hidden under some furry cardboard so you need to probe around a bit to find it. Using a multimeter I probed each of the contacts in the connector until I found one that only had 12V on when the car was in reverse gear. (At this point you hear an odd beeping noise which of course comes from the revesing sensors looking at your legs.....) I then used one of those connectors where you lay the two wires side by side and squeeeeeze the top down to cut into the insulation. Stupidly I put this on the side going to the boot so that it will be hard to take the boot off (but I never plan to!)

If you use the original video wiring then you don't really need an earth (actually 0V - there is no connection to any earth in a car - it has rubber wheels) This is because the video lead already has a 0V connection. I cut my 0V wire off - but tested it beforehand just to be sure!


Cheers

Just to echo James' comments, I also initially fitted mine without the earth, but discovered it by accident however after some time, received noisy images, feedback lines and occasional no signal from the camera - which I blamed on being a cheap ebay job - found it was perfect with a dedicated earth wire.

Had also seen many comments about 'clean' supplies for reversing camera power, so used the canbus switch and powered the camera from ignition live.

Hi Amfalconer

'No signal altogether' suggests that your 0V/Earth connection on the video cable became disconnected. If it happened over time then the connection was probably working loose with vibration, a high resistance connection could also give the other issues you mention as you would be losing power to the camera as well as a high resistance for the video. Using the cameras 0V wire would have restored the connection for the video and the camera power. So your fault was not necessarily 'cured', just bypassed.

Clean supplies are always the best but these days power supplies on electronic equipment are very good - even the cheap stuff from the far east.

Hi James,

It was an intermittent fault, basically resulting in a blue screen on my head unit, all connections were tight as a drum and water/weatherproofed, it had to be checked over.

I actually bought 2 at the time, and was about to replace it with a new one when I tried connecting a dedicated earth, it worked fine and still does 6 months on.

The symptoms were lines on the screen, occasional noise/distortion and occasional 'no image'

Connecting the earth was a 2 min job, so well worth doing when compared to having to remove the bumper!

In that case you would be looking at broken screen wiring in the cable itself, If the new 0V wire cured the problem then there was nothing wrong with the camera or the +12V connection or the inner core of the video cable.

I recently installed one of these
Quite discreet and decent quality. There is a vent on the left hand corner behind the bumper to feed the cable through, but I gave up trying to reach it and drilled a small hole directly behind the number plate light into the boot, repainted, put a grommet in and sealed it. It's more of a gadget than a necessity, but useful when parking in my tight garage.
