These have been fitted for about three weeks.

They were $46 to my front door from ebay. They were colour coded from the box. (close enough for me)

Fitting the display monitor, wiring, masking the bar in four spots with masking tape for accurate measuring and marking out, drilling holes in poly bar and metal bar, fit module and wiring took about three hours.

Very accurate in operation, if it saves a rogue kid in the super market, then I'm all for it.

Once you use them you will see why. They will never replace a drivers intellect but sometimes little kids don't have any (intellect) and for that matter neither do shopping trolleys.

Hope this helps.

Nice neat job, however I think the middle two sensors should be closer together like my
mock up.

Is there set parameters for the sensor location?

yes, usually in the manual that comes with the sensors.

In the instructions it states that the distance between the middle two sensors must be half the distance of the bar width.

This is because the middle two have a wide beam which overlap considerably. Then when the outer sensors are placed just around the corner (or just off level) on the bar, they not only go around the corner, but they overlap the centre ones.

Inner sensors and outer sensors are not created equal. The middle two have a larger flare to overlap and have great distance to the reverse. Each sensor has a separate position in the junction module. If you look at some cars they are wide part and some are close.

I'm happy, I tested them and tested them with a broom pole vertically for width (about 30mm) to check for sensitivity and "pickup" before I drilled the holes.

Its all in the instructions.

Hope this helps.

I got the same reverse sensors pack with four sensors. I took the display apart and installed it in place of my speed alert. ill post pics when i finally get the cord to the camera.

how did you go about connecting it to the reverse lights? this is the only thing i think would be hard.. rest seems pretty easy..

might have to invest in some.. just for the sake of it and they arent all that expensive considering genuine sets are around 400..

Get two wire tappers and tap into the two wires for either of the two reverse lights. What
I did as my reverse lights are in the boot lid, was to feed the wires into the boot lid next to
the right reverse light, removed a little of the rubber sheath of the revers light wires and
removed a section of insulation and soldered the sensor unit wires into it and then taped
it up with electrical weld tape. It would have been easier if it was a 2nd gen as the light
bulb holders are your basic ones which you could unscrew the screws and then screw it
back on with the additional wires. The 3rd gens use custom integrated holders.

When I wired to the revesing lights on a wagon I feed the wires straight under the rear quarter panel, into the rubber grommet at the back of the light cluster.

I then soldered them into the wiring loom and sealed with electrical tape.

Worked a treat.

Hope this helps

What's the closest to the wall it'll let you reach before going max-beserk?? :P

I need to park 2cm from the back wall for my cars to fit inside the square in my garage,
otherwise their noses will be over the line at the front - both sedan & wagon.

Best thing for that is to line up a piece of foam against the wall and either drive up to it or
reverse into it and stop when you see the top of the foam move. 1" thick foam panels are
quite cheap at Clarks Rubber.

I usually park by using the shadows from the lights.

And leave handbrake off so I can give it a little push if needed.
