Installation
Before you begin, make sure that the sensor/keypad cables,
the flasher cables and the 12VDC power supply cable will all
reach the proposed location of the MSU250. Mark the cables
with labels describing where the cable originates (rather than
which terminal on the MSU250 it should connect).
For proper installation, follow the steps outlined below in the
correct order. If you discover a fault in the course of installa-
tion, go on to the Troubleshooting Guide before continuing
with the next installation step.
