Here is the complete Crime Guard 745i Keyless Entry and Security kit.
Now that our 87 D150 project truck is almost complete and were able to drive it, we want to make it secure from predators. We called our friends at Crutchfield to help us pick the best security system for our needs. Crutchfield suggests that we have a system with a two-stage shock sensor, glass tampering sensor, two-stage two-zone motion sensor, starter disable, and keyless entry. Additionally, Crutchfield recommends a separate kit with door lock actuators so the doors will automatically lock when the alarm is set.
Fortunately, we discovered this was a very simple kit to install and is programmable to the owners liking. Follow along and see how its done.

After finding a location on the firewall under the dash to mount the Crime Guard Alarm, we start by finding and labeling the power sources needed. A constant power and an "ignition on" power are needed. Here, a test light helped us locate both positive terminals in the fuse box.

One of the alarm systems wiring harnesses was plugged into the Crime Guard Alarm. The Alarm has up to eight harnesses depending on the accessories.
The Plug-In Easy Valet TM...
The Plug-In Easy ValetTM switch was mounted in a location that is not visible, but is easily accessible to the driver. The multi-purpose switch turns the valet feature of the alarm on and off and also is used to custom program the alarm.

A 5/16 -inch hole was drilled into dash. Here, the Red LED Status Indicator Light was installed with a small screwdriver.

The system comes with a negative and positive dome light trigger for use on different makes of vehicles. This switch activates the alarm when there is a battery draw and turns the dome light on for convenience when the alarm is disabled. The driver's door dome light switch was removed for this connection. Either factory switch will work.
The location for the Dual...
The location for the Dual Zone Radar Sensor is critical. The sensor's ability can be altered by the metal structure of the vehicle, so finding the ideal location is a must. In this photo we mounted the sensor on the front of the heater box away from any metal objects. This sensor provides dual protection inside and outside by transmitting and receiving a radio frequency that responds only to mass objects like a thief's arm entering a window.

This photo shows the Air Pressure Shock and Glass Breakage Sensor. This sensor was mounted to the steering column next to the firewall to ensure proper operation, detecting shock anywhere on the vehicle. A microphone (arrow) was mounted in a central location inside the cab to assist the shock sensor by detecting noises, such as glass breakage.

We installed two pin switches, one under the hood and one for the fiberglass tonneau cover. A 3/8 hole was drilled in the tonneau frame over the post hole.

We wanted to make sure the alarm is heard by everyone. We selected a spot for the siren between the inner and outer front fenders.
The starter interrupt relay...
The starter interrupt relay was wired into place. (arrow a) The ignition side of the starter wire was routed through the relay and here (arrow b) it plugged back into the starter relay. This gives the alarm the ability to disable the starter while the alarm is active and to enable it only when the alarm is properly turned off.
