    Have you used similar cable and is the screening sound from end to end ?

    are these just for the front end or are they 'tagged' into the rear ones ?

    seems strange why the wires arent long enough if just used for the front end.

    Never extend the wiring for the actual sensors. They work by measuring time for the pulse to go from control box to sensor to object and back. If you alter th length of wire from control box to sensor you muck up all the timing.

    that explains it :thumb:

    probably volt drop over such a long run.....thicker cable may help.
    as with anything electrical, the longer the run the thicker the cable for the same results.

    may be worth buying a second set to use independantly at the front and refit the ones you are trying to use at high level rear.

    reversing onto a wooded pitch can cause some high level damage from low branchs etc

    Ooops...just read Daves post above

    I thought they were called eyes.

    I am a tad dumfounded by the use of these things:Sad:, spacial awareness, the use of eyes coupled with a link to the memory and logic functions of your brain are much cheaper and far better than any "sensor".
    When reversing, you should hop out to check your position..perhaps even a couple of times, this saves you hitting anything, and also registers in your memory and feeds the "spacial awareness" side of things, then next time you do it, it will be easier...and so on.

    I am an HGV driver, and over the years, i have driven some huge vehicles with enormous trailers, especially when using low loaders to get cranes into the channel tunnel rail link. Most of the drivers i work with, get out...to check their distances etc...better that than report an accident (the saying is, dont be a ****, take a shunt)....i,ll get out as many times as i need to avoid hitting something, and every time i do, i know that the "information is being processed" for the next time.:thumb:
    Dont give up on your senses just yet, we all lose them much too soon.:Smile:
