    I have just bought a 2009 Zafira after having a 2004 model, I fitted parking sensors to the old model and decided to do the same with the new one. After getting a quote from Vauxhall of over £300.00 fitting them myself seemed to be a good idea.

    So after looking around the forums for information on fitting sensors to a Zafira “B” I found the important information needed missing, things like where to drill the holes, which sensors to use and where to connect the electrics to etc. I know there are a few good posts on here and they were a help in getting me started.

    I spent hours looking at parking sensor kits and in the end my head was spinning, the only thing I did establish was that I wanted angled sensors to take care of the slope on the Zafira bumper and all I wanted was a buzzer warning system ( I had a display unit on the pervious Zafire and found I was looking at the display instead of where I was going), In the end I decided to go for the cheapest one on E-bay £15.39, the idea was that most kits contain the same make of sensors especially the cheap end of the market.

    I ordered the kit on E-bay which arrived two days later. The first thing to do was mark out where I wanted to holes drilling, the “manual” (a piece of A4) that came with the kit recommended 40cm separation between each sensor and 50 cm high, using photos of Zafiras fitted with sensors on this site, I had some idea where they needed to be.

    After finding the centre of the bumper and marking out 40cm spacing I needed to find how far up the bumper I could fit the units, the problem is that there is a metal bumper support behind the plastic bumper, and you need to get as near the top of this without drilling into the top rib. I drilled a 2mm hole 14mm down from the flat top of the plastic bumper, poked a L shaped piece of wire through the hole and checked that I could turn it around, this told me that when I drilled a 22mm hole to accept the sensor I would have no problem fitting it. On the two inner holes I had to drill through the plastic and steel support, whereas the two outer holes I just needed to drill through the plastic. Behind the outer holes the steel support had a slot where the sensor needed to go, also the steel support was far enough back to allow the sensor to sit flush on the bumper.

    When drilling the holes mark out the two centre holes 14mm down from the flat top of the plastic bumper, then take a line through these to get the correct height of the outer sensors, behind the plastic there is a black shock absorbing hard foam you will have to cut this away with a knife, and clean up the inside of the hole to allow the sensor to lock in to the plastic. The 22mm hole borer that came with the kit managed one hole through the steel support but struggles through the second, I suppose that’s what you get with cheap kits, probably drilling a bit slower and using some lubrication would have helped.
    The sensor heads were fitted and rotated so that the sensor face was 90*deg to the floor, the wires gathered up and pushed through a hole I drilled in a plastic plug, near to the left side fuse box, the unit itself was fastened to the side of the fuse compartment, the power supply wires were connected to the reversing lamp supply ( black & white wire) and a brown earth, the buzzer was stuck on the side of the loading bay.

    Turn on the ignition put it in reverse and hey presto it works, in fact it works very well, it picks up anything solid, cardboard boxes, buckets etc and doesn’t give faults warnings. So all in all I’m very happy with my 15 quid’s worth of kit

    Nice work!

    I see you have painted the sensors too for a nice 'factory' look (y)

    Is the Zaf B's bumper not like the Astra H then? When you look on the reverse of the bumper the holes for the sensor's are pre marked and this means you avoid having to measure everything out. Look for 4 circular impression with a '+' marking the centre of each hole.

    don't really know, I didn't take the bumper off. if they are marked you would still have to drill the two centre holes, as I was looking at one with the bumper off in the garage and there were no holes apart from the slots at each end. Plus drilling it with the bumper on saves a lot of time and lessens the chance of scratching the paint work.

    PS: Thinking about it on the Zafira B Vauxhall make a special four sensor plate that fits in the recess at the bottom of the bumper, so there is no provision for fitting sensors in the normal place.

    re reversing sensor fitting

    (y)Hi
    Good photos and very clear instructions.
    I have also bought a chepo reversing system of ebay £15.99 but with my last 08 plate Zafira 1.6 flat as a pancake car i fitted the sensors in the same way and 4 months later some woman rear ended me and it was not a big bump as it was at low speed, My insurance company had a letter of the other drivers insurance company stating they was more damage done to my car due to drilling the reinforcement bar (as that bent where one of the holes were drilled) ,anyway it made no difference to my claim in the end but it held it up for 4 weeks.
    Vauxhall have a kit (£70) and can be found on ebay that fits the rear number plate and has 2 sensors at each side.
    My 58 plate 1.9cdti has one and i fitted it within half an hour and you can take it off when you sell the car .
    I also have a reversing camera fitted so it shows what is behind me using the VXMMI MK2 but it is like a one eyed monster and you can not judge distance with one eye so its quite usless
    I myself do prefer the bumper sensors and they were very easy to fit on the Zafira A (a better car i think than the new model).... so...to drill or not to drill is the question LOL (y)

    re blown fuse

    Hi, you need to disconnect your black and white wires and connect them to your reversing light wires so you need to look at what wires turns on your reverse lights, if you are blowing a fuse it sounds like you are earthing your lights and your earth is simply blowing the fuse....start over and just use your reverse wires and you need to ensure what your black and white wires are for as many kits normally have a black wire and a red wire ..:eh .....>>>>> a simple 12v screwdriver is always handy to have the type with the wire coming off the end...saves time and fuses and makes your neighbours think you know what you are doing,,lol works for me:ROFLMAO:

    Hi, Just a quick one referring to the below quote, If you want to buy parking sensors that are colour coded to your cars colour code then try www.colour-smart.org

    You say easier to fit on zafira A but where abouts did you fit them. Bottom of bumper pointing up. Or top of bumper pointing down ?
