Connect the LMU Harness
Use the following diagram to connect the LMU Controller with the other system components.
Install Signal Connections
Install signal connections as required.
Install and Mount the LMU
With the supplied alcohol wipe, clean the vehicle surface where the LMU will be installed,
ensuring to choose a dry location with easy access to the electrical panel and cable
connections.
The LMU contains a built-in GPS antenna, which can be obstructed by metal objects. The best
place to mount the LMU for optimal GPS reception is
on top
of the front dash panel, with the
label facing out towards the sky.
