Was there ever a factory Alarm Kit for a TJI and does anyone know the part number / cost of it?

Not additional one available as an accessory. I though they were built in with horn as siren. Even my old TH exec had it. Doors locked armed with remote, alarm goes off when doors opened

Sorry - are you saying they're standard with an alarm then? I thought the standard kit was only an immobiliser.

mine is hooked up like that.
if you open the doors without key or pad after its been locked the horn sounds.
