Can anyone supply me with installation/wiring/testing instructions for a Laserline 996 V3 alarm/immobiliser? I've got a BMW (sorry, but it was given to me) with one of these things fitted and something is draining the battery so I need to check out the alarm wiring. Laserline won't help, and a fitter I asked told me that one of the conditions for his VSIB certification is that he can't tell me either. Thanks in anticipation. P.S. I'm happy to pay for it!
