Pressure Switch
To remove a sensor/switch wire from the either J2 or J3
connectors, insert the end of a paper clip into the slot cor-
responding with the wire to be removed. This will depress
the tine on the pin allowing the wire to be pulled from the
harness.
IMPORTANT!
When reinstalling the sensor/switch, make sure the tine on
the pin is lifted so the sensor wire will lock into the connector
body.
