HARNESS CONNECTOR FACES
The connectors, see figure 3, are labeled with
the component they are connected to, or the
connector number from the schematic where
they appear, and their color. The identifying
number is for reference only; it is not the con-
nector part number. For in-line connectors, the
half shown is usually the Socket half. If both
views are shown, the other half is the Pin Half.
Only connectors that have two or more termi-
nals are shown.
if you need to backprobe a connector while it
is on the component, the order of the terminals
must be mentally reversed. The wire color is a
help in this situation. If there is more than one
wire of the same color, you may need to locate a
test point from its terminal number. A useful
trick is to imagine that you are probing a termi-
nal from behind the page you are looking at.
Then mentally locate that terminal with respect
to the keyway or other reference mark.
