Hi Jan, UK cars did not have any factory fitted alarms, or security devices. Later models like my 96 had infra red sensors in both door handles and an infra red key/button. It can also be programmed with a secret code system using the drivers door handle. My 2 JDM cars only have the infra red sensor in the drivers door. I'd be very surprised if there is any wiring in the boot- probs only US of A cars had this? M
