DetailsThe BBUS (battery back up sounder) on the Defender TD5 and TDCi is mounted by Land Rover in a very vulnerable place, without giving too much away it can be disabled without lifting the bonnet and without setting the alarm off Our kit is designed to make it as easy as possible for you to relocate the sounder to a place of your choice or to install a new sounder leaving the existing one as a non functioning decoy. Our kit is totally 'plug and play' with no soldering or crimping required. It is possible to relocate your sounder without drilling any holes or you can be as inventive in its placing as you like. Our kit also includes a 'plug & play' loom to add an additional Genuine bonnet switch (included) to help beef up bonnet security. Optionally we can supply an extra Genuine Land Rover BBUS (battery back up sounder) if you don't want the trouble of touching your existing one and to leave it in its factory location to act as a non functioning decoy. Full easy to follow instructions are included along with pictures of each stage. This kit fits all Factory TD5 and Puma Defenders that are already fitted with a Factory alarm with a BBUS (battery back up sounder) - If you are unsure if your Defender is fitted with a BBUS then google 'Topix Land Rover' and put in your VIN code to check. You may also want to consider fitting a Skytag tracker at the same time for added security.
