The installation of your wire harness mainly consists in two parts:
The physical routing and securing of the wire harness, wires and groups.
The proper connection of the individual circuits.
These two major tasks are not separate steps, but are integrated together. That is, you will route
some wires and make some connections, route some more wire and make some more
connections.
