Wiring guidelines
Most installation problems are caused by shortcuts taken with system cables. When wiring the radar:
DON'T make sharp bends in the cables.
DON'T run cables in a way that allows water to flow down into the connectors.
but
DO make drip and service loops.
DO use cable ties to keep the cables tidy and secure.
DO seal and protect all wiring connections if cables are shortened, lengthened, or re-
terminated.
DO leave room to easily access, install and remove cables.
