Last year, I put a simple alarm on my Hino 195. I chose a universal 12V system from eBay. It required a bit of wiring, but it ended up fitting perfectly. If you're looking for something more straightforward, take a look at brands like Viper or Avital. Just be sure that it's compatible with diesel ignition delays.Has anyone here installed alarms on theirs? any recommendations? maybe something available online. Thanks!
