connector wire needs to be moved from one location to another. Or a
wire needs to be removed entirely. The following guide shows how this is done.
Here are several views of
the pins and wire that is used for the ECM connectors. The arrow points
to the retaining tab. Depressing this tab allows the pin to slide out
of the connector shell. These pins are inserted and removed from
the wire side of the shell.
of the trade, only one of the above is required. The large paper clip
works OK. The center tool is a piece of 1/16" wire flattened and shaped
on the end. The far right tool is a 3/32" x 1-1/2" cotter pin that is
The center tool and the cotter pin work the best. Because they are flat

will need to be removed in order to R&R the pins. These are

There are pin
designators molded into the housings. Although not easy to see in the
picture the arrow is pointing to D16. This is the end location
on that shell. It is important to understand that the D16 is the last
location at the end of the shell. Not the one that it is next too. Note
that there are 16 openings (or locations) on each side, 1

is the orientation of the pin to the shell. The retaining tab is toward
the outside, with the small barrel toward the inside of the shell. When
a pin is being inserted it will click into place. A light tug
on the wire will prove that the retaining tab has locked the pin into

against the tab.
To remove the
grasp the wire and lightly push the wire into the shell. Insert the
removal tool until it stops (gently!). Then pull the wire & pin
from the shell. If the retaining tab is depressed the pin will slide
out without resistance.
The outer holes are to depress the
retaining tab. The inner rows of holes are for the ECM pins.
not push the tool into any of the the inner row openings.
Don't forget to replace the combs once done moving the pins.
