The

LM should be connected directly to a known 12V-DC power source (range of 10 to

24VDC), either the column harness or battery of the vehicle. Although the unit has a built-in

self-resetting fuse, the iLM’s power cable must be fused protected at the power source on

both the RED and WHITE power connections with the 3 amp fuses and fuse holders, included

in the installation kit. Additionally, remember to place the tamper resistant sticker and a tie

wrap over the cover of the fuse holder, as shown in the following picture, so that any

tampering with power source wires can be easily detected.

Use a voltmeter to verify voltage and hook wires as indicated below.

Black

Ground

Red

(fused, 3 Amps)

to vehicle battery, unswitched (+), this wire must

see at least 10 volts at all times, if not the unit will reset continually and send inaccurate

information

White (fused, 3 Amps) To true ignition, 12V switched, there must be

12 volt power in the “on”, “start”, and “run”

position.

All connections at the column harness must be made by either soldering bare wire to bare

wire or using the poke and wrap method.

Note: T-taps, scotch locks, and like connectors are

not permitted and must not be used to tie the iLM to its power source.
