Hello all, first post. I am a tech at a Lexus dealer and as we are not allowed to certify any Lexus with any aftermarket equipment I had to remove a remote start system from a 2005 RX330. From the remote fob it looks like a Viper 5500 but I'm not sure, may be a 5900. The number on the box is VC306392-029. What I need are the installation instructions so I can put it on my 2006 Sienna. I Googled Viper 5500 and found this forum and here I see links to installation instructions for several Viper alarms including the 5900 but no 5500 (Skater Bum). I went to directeddealers but can't access anything there without signing up as a dealer (?) so thought I would post here to see if anyone can help me identify for sure what alarm system I have and where I can get installation instructions for it. Thanks.
