What follows are the steps to install the SmarTire

®

 Trailer-Link

 TPMS system 

components for trailers built after 1998 with integrated power supply lines 
and ABS modules already equipped.  Installation of the TPMS sensors onto 
wheels is excluded in this section.  For additional harness, component, and 
sensor installation details, refer to 

Sections B and E

.

 

CAUTION:  It is recommended to install all Trailer TPMS sensors 

in their pre-assigned locations prior to completing the actions below 

and in accordance with the sensor mounting instructions in 

Section B

.

Step 1. 

For a multi-axle trailer, use 

Figure 3

 to identify the ideal SmarTire 

Trailer-Link ECU mounting location.  To do so, picture a line drawn from the 
left front trailer tire to the rear right trailer tire, and a line drawn from the front 
right to the rear left tire.  Where the lines intersect is the approximate mounting 
location of the provided SmarTire Trailer-Link bracket and ECU.  For a single 
axle trailer, place the ECU slightly in front of the axle.

Figure 14

To ensure optimal signal reception, make sure the distance between any tire 
and the SmarTire Trailer-Link ECU does not exceed six (6) feet.

Step 2.  

To install the SmarTire Trailer-Link ECU mounting bracket, find a 

flat surface at or near the location indicated in Figure 3, and use a minimum 

of three hex bolts to secure the bracket against the surface. Trailer cross 
members are ideal for mounting the bracket.  For dimensions of the mounting 
bracket, please refer to 

Section D

.

Step 3.  

Mount the SmarTire Trailer-Link ECU against the bracket by using 

the two hex bolt sets provided.  Ensure that the ECU module’s flat top is 

facing parallel to the trailer tires, with the harness connector facing away 
from the driving direction.  See mounting example below; arrow shows driving 
direction of the trailer.
