Got a great price on the alarm, about $260.00 and the installation was about $170. So far I'm very pleased. He hooked it up the the glow plug wire so it won't start untill the glow plug light goes out, which only happens the first start of the day. It is also set up for the turbo timer. The distance is great. I parked at the far end of the parking lot while in a department store, while at the far end of the store I was able to start the truck prior to leaving the store...love it!
