My 92 came with the optional TVSS alarm system. Remotes included but no instructions and the PO did not know how to program it. Did a bit of searching and found some decent links but I would really like to find a manual on the full bit. Especially like to get it out of that annoying passive mode.

I also found this TVSS thread too but the remotes and operation are a bit different. Mine looks like the pic posted in the first link. Remotes are black and look like the RS3000 remotes. Unit mounted under the seat looks like the second link.
