(1) Disconnect sensor pigtail harness (3–way connector)
from main engine wiring harness.
(2) Remove sensor mounting bolt.
(3) Remove wire shield and sensor.
4.0L engines with automatic transmission:
New replacement sensors will be equipped with a
paper spacer glued to bottom of sensor. If installing
(returning) a used sensor to vehicle, a new paper
spacer must be installed to bottom of sensor. This
spacer will be ground off the first time engine is
started. If spacer is not used, sensor will be broken
the first time engine is started.
(1) New Sensors: Be sure paper spacer is installed
to bottom of sensor. If not, obtain spacer
(2) Used Sensors: Clean bottom of sensor and
install spacer PN05252229.
(3) Install sensor into transmission bellhousing
(4) Position sensor wire shield to sensor .
(5) Push sensor against flywheel/drive plate. With
sensor pushed against flywheel/drive plate, tighten
mounting bolt to 7 N·m (60 in. lbs.) torque.
(6) Route sensor wiring harness into wire shield.
(7) Connect sensor pigtail harness electrical connector
to main wiring harnes
After viewing the diagrams (1999 model), it's 1 bolt holding it on .
Return the junk you bought from Autozone , and buy a Mopar sensor . Here's one reason http://www.jeepforum.com/forum/f13/intermittent-crank-position-sensor-821891/
As for the wiring issue with separate wires , makes no sense to me , they are all connected to only one pigtail
