3 Tractor Interface Module Installation Guide
3. Install the TIM-SI-SI
In this step, you will use the supplied locking tape to
physically mount the TIM-SI unit in the vehicle. Before
applying the adhesive side of the tape to a surface,
the surface should be free and clear of any oil, dust or
other materials. A primer swab is supplied to clean the
surface prior to mounting.
To open the primer, squeeze the vial at the center
where a round dot is located. Use the tape primer to
clean the mounting surface on the back of the TIM-SI
and the desired mounting location. Next, peal the Dual
Locking Mushroom head Tape adhesive back strip and
adhere a piece to each end of the back of the TIM-
SI (see example photo). Mount the mating pieces to
the TIM-SI and then remove the backing adhesive strip.
Press the TIM-SI firmly to set the adhesive.Press the
TIM firmly to set the adhesive.
4. Install the cable between the TIM-SI
and the OBC.
Both power and the alert Output signal are run through
this cable (eliminates the need for a separate power cable).
4a. Plug the USB Type A end of the cable into the
“+12VDC Alert” connector on the left side of the
TIM-SI-SI.
4b. Connect the pigtail end of the cable to the OBC
and power.
„ „ Black Wire: Chassis Ground
„ „ Red Wire: +12VDC ignition power; 0.15
Amps Max
White Wire: Alert Output; connect to the
OBC Switch Input
„ „ Green Wire : Optional Tamper Detect Output;
connect to a different OBC Switch input. A
100K ohm resistor must also be connected
between the switch input and +12VDC power
(battery or ignition);
5. Install the GPS Antenna and Plug
into the TIM-SI.
Mount the GPS antenna in any orientation where is has a
good view of the sky usually near the windshield or on the
dashboard is a good location. It can be mounted using
the provided adhesive tape or if mounted externally on a
metallic surface (internal magnet will hold in place).
Plug the GPS cable into the “GPS” connector and turn
the nut until it is finger tight + 1/8 turn with a wrench.
