6.3 STEP 1: INSTALLING THE RECEIVER AND DISPLAY
1. The Wireless Gateway Receiver has a built-in antenna capable of receiving wireless
signals from various sensor types, including tire sensors. It should be externally mounted
to the vehicle’s chassis or frame rail near the front of the vehicle and in a position as
close to the vehicle’s centerline as possible. The Receiver can be mounted with the
connectors facing downwards or upwards (to protect cables from ground effects damage)
and it must always be within clear line of sight of the front wheels.
Using the integrated bolt holes and two ¼ -20 (M6X1) Flange Head Cap screws, attach
the receiver to the vehicle. The supplied mounting plate (PN 264.0318) can be used with
existing bolts / bolt holes to mount the receiver (see picture). Torque to 7-10 FT/LBS (13
Nm). For location testing, heavy-duty safety straps may also be temporarily used.
Note: To protect the receiver input cables from any ground effects damage it is also permissible
to mount the receiver upside down as seen below (cables exiting out the top):
2. With the vehicle’s power turned OFF, connect the wiring harness to the main connector
on the receiver (see P1 in vehicle wiring harness: Light – 260.0309 diagram). Route the
J1939 bus and power line through the chassis towards the driver’s cab and dashboard
area. Identify Power line VIN and Ground line GND in the vehicle wiring harness diagram
and connect the power line to a 5 Amp fuse protected, ignition keyed 12 or 24 Volt
power source. Ensure that this power source is properly grounded through the GND
line.
For more information, please refer to the circuit diagram in your vehicle specific manual.
3. Run the display cable (see P5 in vehicle wiring harness: Light – 260.0309 diagram) from
the wiring harness to the desired location on the dash or consol (may require drilling a
hole in the dash). For systems using a 2" SmarTire
™
display, use the dashboard lock ring
and metal spring to secure the display in the dash (may require the cutting of a 2-1/8" (54
mm) port hole in the dash – see picture, also cut a small notch into the bottom of the hole
to create a turn stop. Insert the gauge so that the tab at the bottom fits into the notch. If
the lock ring cannot be engaged, either remove the metal spring completely or bend it flat
