If like me you have a Fiesta with a 6000 series CD player but no AUX socket fitted as standard, with a little modification you can easily install the Ford approved socket for under £30. This will give you a 3.5mm input jack allowing connection to the majority of portable music devices such as a mobile phone or iPod etc.
Parking sensors act as a useful parking aid (great for in the City), a handy gadget and also a good way to add value to your vehicle. Ford fit Xvision Sensors (part #1420032) at the factory, and an after market install on a Fiesta is generally in the order of £200.
You can purchase the part and fit yourself, although the best price I could find was ~ £110 for the kit alone.
I was keen to fit them myself, but wasn't convinced the Xvision kit was the best in terms of both price and features.
After much research I settled on a kit from Dolphin (DMS400SBLK) which ticked all the boxes, and was a great price to boot (under £70 for everything). The image on the left shows the kit, including four micro sensors, box of tricks, buzzer, hole saw and manual.
I wanted to be sure that everything was going to operate as expected before drilling any holes or cutting any wires. With the sensors taped onto the bumper, I was able to push the +12vdc wire into the reversing light terminal to test.
With the car in reverse and the electrics on, after touching the ground wire for the box of tricks on one of the cars grounding nuts, it all sprang into life.
It's worth testing each sensor is operating as expected individually, and this also gives you an idea of the detection range. I also suggest testing here with the engine running, to iron out any later complications with powering.
I find drilling holes in my car a little unnerving, so I spent a good hour or so just marking up where to mount the sensors. The micro sensors in the above kit are 20mm in diameter, and need approximately 20-30mm depth (which includes a bit of space for the cable). You'll need to check that there is suitable clearance behind the bumper, as there are sometimes metal bars immediately behind that may get in the way.
On the Fiesta, there's plenty of space behind, so much so that in the end I didn't even remove the bumper throughout the whole fitting. The picture to the left shows how I used masking tape to align the mounting locations - the instructions say mounting them 30-40cm apart, 40-70cm off the ground. Apart from that (and avoiding tow hooks etc) it's up to you.
Marking up the locations was easier said than done, mainly because the bumper didn't really have any square edges to align to! I found marking cm intervals onto pieces of masking tape and running them from the top to half way down the bumper was useful.
Once they're all marked up I used a sharp point to create a pilot hole, then progressively larger drill bits. Then, with the drill at quite a high speed the provided hole saw goes easily through the bumper - just leave it to do it's work without apply too much pressure. Adding extra masking tape around where you're drilling is useful to prevent any scratches.
The picture to the right shows all four holes drilled - definitely time for a tea break!
You'll need to run the four ~ 5mm cables for the sensors from your bumper into the boot. I thought this was going to be a case of feeding it through some grommets, but on taking out all the interior carpet on the left hand side of the boot I found a gaping hole to the bumper through which I could have fed a small animal (I'm not convinced that it's meant to be like that)!
Once you have an appropriate route you can feed the sensor cables through the holes (depending if you took the bumper off or not - in my case I fed the cables in from the outside, and pulled them through from under the car). It's worth marking which cable is which sensor (although unless you have the model with a display, this isn't essential).
I ran all the cables through and attached the sensors (but didn't secure them into the holes yet, in case any adjustments to cable connections were needed later.
The kit requires a +12vdc feed, and only needs to be powered whilst your car is in reverse. You'll want to take the +12vdc feed off the reverse wire on the rear light block, taking ground to the nearest grounding bolt.
In the MK6 fiesta this is the green with orange tracer wire going into the rear light assembly, into the junction marked '5' on the plastic socket (pictured right, the solid red wire goes to the box of tricks).
Your Haynes manual is valuable here as it clearly shows which wire is the right one. It's worth doing your research here, as some cars carry coded information, or may send pulses for bulb blown detection etc. Therefore, you might not be able to take the feed directly - see the Dolphin site for more details.
Originally I was planning to cut the reverse wire and splice off, but in the end just jamming in the +12vdc line into the connector and fixing in place worked out fine.
I also added an inline fuse holder with a 1A quick blow fuse on the +12vdc line for a bit of added protection.
I chose to mount the box of tricks down in the spare wheel well, so it's nicely out of sight but accessible.
There's plenty of space and lots of useful channels for running through all the cables.
The kit comes with good quality double sided pads for both the box of tricks and the buzzer, so no need to drill any more holes!
It's worth noting that the buzzer is surprisingly loud, so even when mounted in the boot with a parcel shelf it's perfectly audible.
I opted to mount the buzzer on the plastic just under the parcel shelf mount, so the cables run behind the interior carpet.
