Cheers, mate, perfect guide, have to say hacking four holes in to the rear bumper got the heart going for a min but after the first one went in perfect it was a doddle and exactly as you described, only difference was I didn't need to remove the full plastic side panel, just loosened it up and was able to remove the side fabric panel without any bother, may have even found a couple of the annoying noises I keep hearing,

 

Found something intresting though, seemed the previous owner may have had something on previously as there was some evidence of wiring running about and spliced wires, curious to what it was because it looked like the break lights / indicators and tail lights were all tapped in to at some point... anywho  rear sensors work a treat and look the business, £16 well spent.

I suspect with that description of tapping in, they had a towbar and an electrics relay for the trailer.

aye, it must have been, would have been nice if they bothered to tape up the exposed wires though

did they solder them in? you could just remove the exposed wires, and the best thing I could recommend is to get some emalgamating tape and just wrap the exposed part of the wire in it.

yeah, I tapped them up, blind luck it didn't start shorting out on things as they weren't secured in any way, think ill check the other side out too, maybe look for more noises whilst im there and pop in a spare 12v socket for good measure.

I'm at the stage of marking the spot to drill on my mk 2.5. I can see the circles behind the bumper, but I'm having trouble finding a way to mark it from the inside. Anyone any suggestions? Or measurements from the outside?

I got a caliper working out the measurements, then set a protractor to the same diameter and draw a circle on a piece of paper. The hole is your guide, line the circle up, us a pencil in the hole and ta daa, thats your guide, I used a knife to push outwards making the raised bump on the outside did the same on the outside to mark your drill point and off you go

guestimate is enough. All I did was aimed for the centre of the circle and used a tiny drill bit to drill a hole from the back of the bumper through the middle and to the outside as a pilot gauge. then I just adjusted visually from the other side, so one or two of the holes where a little too high, I just moved the cutter bit a little to relflect it and go from there :)

 

It was easy and did a very good job, better than doing nothing at all!

I did something similar to James. I got a sharp nail and pushed it through the middle of each circle from the back of the bumper (rear bumper still on the car) until i could see it starting to make an indent on the outside. Then i just drilled the indent from the outside right through with the correct size drill to suit the size of the parking sensor. My drill bit came with my sensor set.

Thanks for posting this guide. I ordered the kit on Friday and fitted it in a couple of hours on Saturday thanks to the superb instructions in your guide. I have a factory fitted diffuser fitted at the rear and was expecting problems fitting the kit but your images and description led me through the process step by step

HI chaps.

 

I have read every page of the 14 pages of this thread so far due to my keeness to install some of these sensors.

 

I had 2 questions to ask and have come up with further questions due to the lack of clarity in the reply, so maybe you guys can help me here.  I'll explain:

 

I have a standard FOCUS 1.8 Titanium TDCI Silver 2008.  I assume this means its the mk2.5, and 'moondust silver' is the official name of the colour.  Please correct me if these assumptions are wrong.

 

First I wanted to know whether the BEEP BEEP sound comes out of the black box (control unit, going in the boot) or whether its actually from the LCD screen.  So i contacted the supplier on ebay (as posted and referred to by Preee) who informed me that the sound came out of the LCD unit. 

 

Quote:

"Hi, it is the display that does the beeping. The sound is not loud enough to be heard from the front if it was placed in the boot, as it's not designed that way. 

 
We have a newly designed buzzer kit, and you place the buzzer in the boot and it's loud. See item number below:
 
370661224258"
 

I then decided that the LCD unit wasnt for me (no place for it, will 'clutter' the inside of my car, and generally like most of standard fitted cars isnt necessariliy necessary).  So I would like to take the 'audio only' version.  So reading this thread further it seems that the 'audio only' version does have a significantly loud beep to compensate being buroied in the back of the boot.

 

QUESTION1:  Can you confirm this?  Is the audio only version (without the LCD screen) loud enough to rely on without frustrations if installed and positioned where Preee has suggested?  And where is the 'speaker' installed in such an occasion?  Still in the boot at the side of the main black unit?

 

In the email you can see he pointed me to a 'new modern' model specifically for a CANBUS car (which is £3 more).  I am not sure whether this is relevant to me (Im not fully understanding this CANBUS thing and whether my car cares regarding the reversing light. I do know a simple LED replacement bulb DIDNT work in my reversing light but did on an older car which I concluded it must be this CANBUS incompatibility thing).  So has anyone else bothered with this.

 

So, QUESTION2:  Am I safe to just take the 'non-canbus specified' version (such as http://www.ebay.co.u...and discussion)

 

(Question 3:  Is the 'silver' from these CISBO sensors really a good enough match for my silver 2008 focus, in your opinion?)

 

I hope this makes sense, thanks for your help.

I hope this makes sense, thanks for your help.

Q1 The Audio without the panels on is like a small bomb going off, with the panel on and the buzzer right in the back corner, you can hear it a plenty, put some music on as well if you like.

Q2 no idea, I cant for the life of me see why it wouldn't work, its just drawing a few mA more on the revers light, hell I have spliced on not only a second reverse light but also the wee ford badge and reverse sensors of it without any bother but im not an expert on these things. on second thoughts, doesn't the trailer light connector just run off those wires as well? if slapping a trailer on doesn't create a problem im sure this wont, I always thought that the problem was if the wire draws too little current, ie LEDs, it thinks its broken.

Q3 The silver is a spot on match, my partner thought id taken it to Ford to do and was giving me grief for shelling out £200 on it, I was sitting there beaming from ear to ear as she thought it was that good!

:)

Cheers Dee for 'Darren'!  I think your analysis of the current (and LEDs being too little) explains why the LED light bulb I bought simply doesnt didnt work (I gave it away).  I will go for the standard audio-only set then and hope its all good.  You hapy with yours?  (The 'Bi-bi-beeeep' working well within the distances?  Where did you get yours from (got a link?).

 

I suppose I am not the only one that thinks that sticking a single standard reversing light rather than a double, in the opposite corner, on a car with blackened windows, is just a ridiculous concept and made it practically pointless. At night, where I live and park on a communal yard, I have to turn on my fog lights when reversing to give that extra chance of not hitting the other cars. (I see the recent model of focus they have FINALLY realised and installed 2x reversing lights).  To add my own insult into my existing injury I even paid to replace a faulty reversing-switch on the gear box in August just to give me that candles-worth of light.  At least if I get these sensors that switch replacement will be more justified.

Im happy with shelling out 16 quid on it!

It isn't 100% perfect, if reversing down a slope it can get a bit excited, if its !Removed! down with rain it can sometimes get a bit "twitchy" in that it can have a moment or two before it sorts its self out, usually just beeps for no apparent reason, taking it out of reverse and putting back in again usually sorts it. the angle on the two side sensors is such that if your backing in to a drive with a hedge on the side its close enough to get it beeping, I don't think better units would handle much of that any better, perhaps the rain might not impact on it so much.

Anyhow, its a steal for £16 and have no regrets or thoughts of upgrading it.

The distances got me a little nervy to start with, but I think that's more to do with me only just getting a Focus, with its bigger back end it felt like I was getting way to close but on single beep your getting about 2.5-3 foot, progresses to single tone at around 20cm, never came close to hitting anything.

The second light is a god send, my drive is black at night and the rear of the car is about 15CM from a hedge on one side and the house on the other, I could see the hedge fine but the house was a problem and because of the hedge I cant rely on the reverse sensors. used to have to just line up on the hedge and hope to miss the house, so second reverse lamp went in, connected up a Cree to them both and its sorted, next job is to finish off the other side by adding a second fog light
