Connection for existing OEMharness
Tip – Proper connection depends on your configuration. Reference the TMX-2050 Display Cabling Guide for
appropriate information.
The following graphic shows how to connect the TMX-2050 display and TM-200 Module to a vehicle
with an OEM connection. See the TMX-2050 display Cabling Guide for connection instructions on
specific configurations.
CAUTION – If the vehicle has a master electrical disconnect, make sure the power cable ground connections are
not directly attached to the battery terminal. Attach the ground connections of the power cable to the chassis
side of the main disconnect so that it is as close as possible to the battery, but still gets disconnected when the
master disconnect is turned off. Failure to connect the power cable ground will cause damage to the display.
CAUTION – Make sure the vehicle power is off when you are connecting system components.
