    Installing Cruise Control On Discovery SII

    Hi,
    I joined this forum a couple of weeks ago when I bought my 230,000 km 2002 TD5 Discovery Series II manual - a private import from Britain.

    After researching on this & other web sites I decided to try installing cruise control - assuming that people were correct when they said I'd only need to install the switches.

    They were dead right!

    I ordered the switches from the UK & installed them yesterday - and now I have a responsive cruise control with no other work required! All wiring required was already in place & only needed to cut a hole in the plastic steering wheel shroud.

    One word of warning - cutting the hole in the steering wheel plastic for the set/resume switches is time consuming and DON'T be tempted to drill with a large bit. I looked at the supplied template & then removed the audio switches on the LHS of the wheel to check it & made my own instead (the supplied template was a little larger than needed but would work OK).

    I looked at the radius of the corners of the template & thought it would be easiest to use a 1/2 inch bit in each corner to start. Bad move. The bit grabbed when it was nearly through and cracked the 11 year old plastic! Not too bad - a bit of super glue to hold it together & the rubber boot hides most of it.

    As I have a Dremel clone, I then used that to cut the hole. Cutting disc for straight lines & then sanding cylinders to shape the hole. Laid an old towel aroud the area to catch the plastic crumbs (but still got some on the windscreen). This was much better.

    Well done mate.

    That will work on some but not others. Mine is a base model, so no throttle body gear. If I was doing to the expense of sourcing that gear, I would be better off with an Autronic or similar.

    Cheers

    Hi guys,

    how can you tell if there is cabling ready for the cruise control or not?

    Sounds like it was a good project and I might do the same.

    The Discovery is a strange vehicle (may be all Land Rovers) in that they seem to have put the wiring for most features into most vehicles. Most other manufacturers have multiple wiring looms to fit depending on the option level of the vehicle, but with the Discovery, it seems that they tended to get the wiring for everything!

    It's not simple of just installing switches, as the D2 works on an electrical operated vacuum pump, from this actuator pump and bellow comes the cruise control throttle body cable. With out these Vital components there is no cruise.Some may have been lucky to already have the cable and vacuum pump installed, then all it would need is switches to activate the system.

    Just in case any one missed it, the original poster was talking about fitting cruise control switches to a Td5.

    The Td5 cruise control is part of the software in the engine ECU and has no external components apart from the binnacle and steering wheel switches. The wiring for both the stereo and cruise control steering wheel controls is fitted to all vehicles, as is the harness for the binnacle switch. So on the Td5 it is just a matter of installing the switches.

    cheers
    Paul
