Multiple Wire Connectors
Although the simple wiring terminals just described
are really wire connectors, the term connector is
normally used to describe multiple-wire connector
plugs. This type of plug is used to connect wiring to
switches, as shown in Figure 6-14, or to other components.
It also is used to join wiring harnesses.
Multiple-wire connectors are sometimes called
junction blocks. On older vehicles, a junction block
was a stationary plastic connector with terminals set
into it, in which individual wires were plugged or
screwed in place. Because of the time required to
connect this type of junction block on the assembly
line, it has been replaced by a modem version that
accepts several plugs from different harnesses
(Figure 6-15).
Some multiple-connector plugs have as many as
40 separate connections in a single plug. They provide
a compact, efficient way to connect wires for

wires on one side and connectors on the other.

individual circuits while still grouping them
together in harnesses. Wiring connections can be
made quickly and accurately with multiple connectors,
an important consideration in assembly-line
manufacturing.
