Installation Guide

What's Included

MF4315 Device

3 Wire Install

1. Locate your vehicle’s unswitched 3-wire:

1) 12V/24V power line
2) Ignition sense (greater than 9V),
3) Ground line

Verify that the ignition sense exceeds 9 volts when on.

*For best results, it is strongly recommended that the device connection be on its own circuit. If possible, connect the power input directly to the vehicle battery and protect the circuit with an InLine fuse. If you must connect through the fuse box, use standard commercial wiring practices to create a permanent installation rather than using press-in fuse clips or other temporary measures.

2. Connect black wire to vehicle’s ground line.

*Must be connected to chassis ground.

3. Connect red wire to vehicle’s primary power source.

*Must be connected to a constant (unswitched) +12 VDC or +24 VDC supply. The preferred method is to connect directly to the vehicle battery terminal line.

4. Connect white wire to vehicle’s ignition line.

*The ignition line must be connected to the vehicle ignition or another appropriate key operated line, such as ACCESSORY, ensuring that power to the ignition wire is available only when the vehicle ignition is on.
