In this post I will try my best to explain where which wire goes, relative to my install.
Keep in mind that this is specific to the DEI Responder LC3 brain (Viper 5901, Clifford Matrix 50.7X, etc).
Keep in mind I will not be using any of the dome light supervision/flash functions, because I do not have a dome light. Nor will I be using/setting up remote start. I also do not have power door locks, so this write-up will not cover any of that.
All the Constant 12+ wires will be ran together when I do the install. The Ultrasonic 509U sensor does not come with a fuse, but I will install a inline 1amp fuse when I do the wiring/install.
All Instant Trigger/Blue wires will be ran together and connected to the H1/7 wire on the main harness. A small 1amp diode will be needed on each trigger wire (Radio Shack Part Numbers: 1N4001, 1N4004, 1N4007). This is to reduce interference/weird things happening with the alarm/problems with the sensors seeing power in the wrong place.Tilt Sensor:
Red: Constant 12+ (Fused, 1amp).
Blue: Instant Trigger. H1/7 Blue on Main Harness. Needs 1amp diode.
Orange: (-) Ground-When-Armed. Orange wire (H1/12) on Main Harness.Ultrasonic Sensor:
Plug straight into extra sensor port on Alarm brain.
Red: Constant 12+.
Black: Chassis Ground.
Blue: Instant trigger.Back-Up Battery Sensor:
Red (Fused, 15amp): Constant 12+.
Grey: 12+ Output. Run to Constant 12+ input of alarm brain, H1/2 on main harness.
Red (Middle): Run to red wire/connector on the back-up battery itself.
Black (Middle): Run to black wire/connector on the back-up battery itself.
Black (Outer): Ground.
Blue: Instant trigger. Run to H1/7 Blue on Main Harness. Needs 1amp diode.
Alternatively, here is a wiring diagram provided by DEI for the 520T:
