Gary, there would be no way for us to tell you how to wire a motion sensor to your factory alarm because most dealerships use aftermarket alarm installers to install alarms into vehicles that they sell. That being said, we wouldn’t know what kind of alarm is in your 2005 Chevrolet Silverado C1500. Our advice is to take your 2005 Chevrolet Silverado C1500 to an experienced alarm installer and they should be able to install the motion sensor for a minimal cost. Hope this helps. Good luck.
I bought a Dual Zone radar sensor to install in the back of pick-up cap cause I recently lost all my shotgun and archery equip taken from from a sprung cap window.Thought a Sytec motion detctor would be best option and it was to have wiring diagram……not. How do you connect to existing 05 siverado alrms system….(in laymans terms please). It is 4 wire blk- ground, red 12+, greenextreior trigger, blue interior trigger…..thats all I got…………help
thanx gary
