I put an Internatrix in my T100, 2 years ago. Installed it myself.
Satisfied, and it does everything as advertised.
Model TW-400. I remember it cost me like $149 in the door.
Perimeter alarm and it TALKS !
Passers by people, usualy walk by it 2-3 times just to hear the T100 talk. - Can be a bummer.
Insurance gave me 10% discount off policy catagory as well.
Immobiliser, perimeter alarm, remote, talks option, headlight and turns lights flash, chirps, flashing alarmed LED - mounts in my T100 dash as is in the Triumph hole, vibration sensor, main unit fit under my stock and K&Q seats no problem while I mounted controls behind side cover. Every thing but a backup battery. Scares the jump'n fur off my cats...
