INSTALLATION NOTE:
Exposed connectors may be placed inside of connector box on security cabinet.
Tampering could be further reduced by using metal conduit to route exposed wires into
vehicle body. All wires should be protected from the inside and outside areas of the
vehicle. Convoluted split loom should be used in all other areas to further protect the
wires. All wire connections should be splice soldered and insulated or lugged.
