The alarm is about 150.00 dealer cost less if you get a deal... You can install them just ask NOSBUSA for the 12volt print out of wires and where to find them there is a website. It will tell you wire color connector it comes off of and color of connector and location of connector. It takes a little time this is why retail guys charge so much to do the install..... You can order proximity sensor and microwave motion sensor, tilt, impact, and a whole host of options. The two way remote os great, but the screens break. They usually are limited to about 2000 feet range, beyond that your not going to get there in a run no matter what anyways... To protect lights and stop them from being unbolted just put a small tack weld on the threads. This prevents theft becuase thieves dont hang around to make a bunch of noise while trying to get the weld bead off...... Been doing this trick to protect my winch for years... no not my wife, she gets mad if I call her a *****,,,, ..... .... ...
