HOW-TO: Install Reverse Parking Sensor [lots of pics]

Postby LostyJai » Sun Jul 01, 2012 2:13 am

Hey guys,

I also used a few pages from the service manual which helped me remove the rear bumper, it's here (https://dl.dropbox.com/u/11792766/forum/Parking%20Sensor/Bumper_Removal.pdf) if you want it.

I wanted to get some reverse parking sensors on my Liberty but I thought it costed too much ($300 fitted from Strathfield), so I ended up having a look on eBay and they only cost $30 (Strathfield was selling them for $200)!!! So I ended up getting it from eBay (http://www.ebay.com.au/itm/110804420684), picked the silver to match my car and decided to give it a go installing it myself.

Turned out to be quite easy and enjoyable experience, now I feel more comfortable modding the Liberty.

So I connected the sensor up when I bought them to test that it was working.

Image

Seems like it worked fine, so I went over to my mate's place and he gave me a hand installing it. I'll try explain as much as I can remember.

Inside the boot you will see a plastic panel attached to the trimming, the top one you just turn with a flat head screwdriver and bottom one you press in and it should pop out. The right one you get it out by spinning it towards the middle of the car.

Image

The inside trimming will have a few plastic bolts that you need to pull out, we used a flat head screwdriver to pry them out. Apologies for the blurry photo.

Image

You will also need to remove the trimming across the back of the boot, that you can just pull off once the plastic bolts are out.

Image

Once all the fittings have been removed, you can gently remove the inside trimming to get to the back of the rear light unit. Be careful of the hinge(?) for the bonnet, we had to bend the trimming a bit to get it under the hinge.

Image

Having removed the trimming, you will need to unscrew the 4 bolts to pull the rear light unit out (the white cable ties that is attached to the bolts you can just pull off), then just disconnect the power and carefully pull it out.

Image

Image

The reverse parking sensor is meant to only turn on when the car is in reverse gear, therefore to achieve this we need to piggy-back the wires of the power cable provided off the reverse parking lights. Before I went any further I wanted to test that it everything would work as it should so I connected the power cable directly into the reverse light socket.

Image

After connecting the wires I put the car into reverse and I could hear the sensors beeping so I knew it was working. I wasn't too keen on splicing the wires or soldering it, so I just shoved the cable into the socket as much as I could (it felt like it wasn't going to budge) and then just taped it up with electrical tape. (Yes I know it's quite ghetto, but it'll be easy to get to)

Image

Finally we are ready to take the bumper off!!! Start with the pop screws where the rear light unit was sitting, just get a flat head screwdriver and pop them out.

Image

Some more under the car near the exhuast.

Image

There is one bolt on the inside of the boot, on both sides.

Image

The last and most annoying bolt is hidden behind the plastic around the arc of the wheel. I forgot if we undid that plastic bolt, but either way you just carefully pull that plastic off to get to the last bolt.

Image

It is a 10mm bolt and you need to use a spanner, lucky I have small fingers and could reach it. X marks the spot!

ImageImage

That should be all the bolts. Now pull out the sides of the bumper, and then carefully (try not to use too much force) and lift the bumper up which should pull it out and free it from the plastic teeth like locking mechanism (shrugs).

Image

TADA! Bumper off! Give yourself a pat on the back and have a beer (or 6).

Image

The next bit we kind of winged it and did the best we could with some cloth tape, plastic 30cm ruler and a texta. Marked it out, used the drillbit provided and drilled the sucker! Hopefully you will be more prepared!!!

Image

I decided I want to put the LCD display on top of the dash (driver side) just behind the air vent. The tricky part is figuring out how to get the wire from the boot to the front and hide it, but it was actually quite easy once I figured out how to get the cable into the cabin.

What I used was a clothes hangar, made a little hook and poked it from the boot to the right hand passenger seat... as you can see in the picture.

Image

I used the hook to pull the LCD display cable from the cabin into the boot from the passenger seat. When doing this be careful not to scratch that sexy leather!!!

Image

Now that you've got the cable into the cabin, I would recommend you work at hiding the cable from the front then to the back of the car. Like I said I wanted to mount mine just behind the mini vent, and lucky for me that plastic was quite easy to take out which made it a lot easier to hide the wire.

Image

Work your way towards the back of the car and hide the cable as best as you can. Shouldn't be too hard if you lift up the trimming (?) with a flat head screw driver and just push the cables in.

Image

The side of the rear passenger seat is a plastic fitting which you will need to get the cable around it. If you pull the seat up a bit you should see it and then you can pull the cable around it.

Image

Image

The cable inside the cabin should be all tucked away nicely. With the boot it doesn't matter too much as the wires will behind the boot trimming, out of sight out of mind.

Image

Now you will need to fit the bumper back on and pull all the wires through the holes of the rear head light unit.

Image

Finally just tidy up all the cables and decide where you want to put the main unit. I put mine behind the rear light unit which fits nicely behind the trimming and is stuck on with the double sided tape provided.

Image

Woohoo new reverse parking sensor! As my work colleague would say, "J.D!!!" (Job Done!)

I hope this install will be useful for those that wish to the same on their car. Good luck and thank you for reading!

Awesome! Wishing there was a similar how-to for wagons, but this is a great start!

Awesome work Simon, looks great. Thank's for pointing me to your walk through.

Ben if someone doesn't beat me to it I can add (if that's ok with you Simon) to this how to on the differences for a wagon. I will be ordering the same unit soon.

Also how did you found the silver colour sensors up against your bumper ? Is the colour close enough

By all means, go for it Alex! We're just all here to learn from each other :)

Yeah it looked close enough to me man, but then again I'm a little bit colour blind :lol:

Losty,
I can't thank you enough for this tutorial.
I bought the kit several months ago and just got around to installing it this week. Definitely couldn't have done it without your post, so thanks again.

I grabbed the 'silver' colour for a face lift gen 4, but the colour doesn't match up quite as well as yours, looking at it now I should have gotten the iron grey. It is a little daunting to see the car with the whole rear bumper off (especially this one, because in a previous lift it looks like it has spent a lot of time on dirt and at first glance looked very rusty).

There were two slight differences with the facelift gen 4's, the clips below the tail lights are different, the bumper clips / attaches over the black support bars and does not use clips as such. Very straight forward to release once the lights are out. A picture of the black support beams below. The other difference is the two side 'fins' are in the way of where you positioned your sensors, so instead we raised them up (I searched on here for a picture of a facelift with sensors installed and matched). I should have got some better photos at the time.
