2 Install and Mount the LMU Controller
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.
